Standard method for batch files to handle errors is to use <a href="http://ss64.com/nt/errorlevel.html" rel="noreferrer">ERRORLEVEL</a> variable. Zero means no errors, non-zero - error:

<pre><code>@rem some code
if %ERRORLEVEL% neq 0 goto ProcessError

@rem ... other code
exit /b 0

:ProcessError
@rem process error
exit /b 1
</code></pre>

<a href="http://ss64.com/nt/exit.html" rel="noreferrer">exit /b exitCode</a> sets ERRORLEVEL to this exitCode.

<code>TIME</code> is a magic variable which returns the current system time in user's format unless it is overridden by an ordinary environment variable set by the user.
In other words, use something other than <code>time</code> as the variable-name.
As for the error, it would help if you were to show us what the error was.
Now you could try
<pre><code>set &quot;mytime=&quot;
for /F &quot;usebackq tokens=1,2 delims==&quot; %%i in (`wmic os get LocalDateTime /VALUE 2^&gt;NUL`) do if '.%%i.'=='.LocalDateTime.' set myTIME=%%j
if defined mytime (set myTIME=%myTIME:~0,12%) else (
 echo error - WMIC failed to execute - perhaps it's not in your PATH&amp;goto :eof
)
</code></pre>
Noting that WMIC is not installed by default in XP/Home (and by implication, possibly earlier versions too)

blocks|key|307016|text|这与时间无关，但与wmic和错误处理有关。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|307017|这可能对某人有帮助。|307018|FOR+/F+"tokens=2+delims=="+%25%25I+IN+(

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
:::DOCUMENTATION:::

EXCEPTION.BAT+is+a+pure+batch+script+utility+that+provides+robust+exception
handling+within+batch+scripts.+It+enables+code+to+be+placed+in+TRY/CATCH+blocks.
If+no+exception+is+thrown,+then+only+code+within+the+TRY+block+is+executed.
If+an+exception+is+thrown,+the+batch+CALL+stack+is+popped+repeatedly+until+it
reaches+an+active+TRY+block,+at+which+point+control+is+passed+to+the+associated
CATCH+block+and+normal+processing+resumes+from+that+point.+Code+within+a+CATCH
block+is+ignored+unless+an+exception+is+thrown.

An+exception+may+be+caught+in+a+different+script+from+where+it+was+thrown.

If+no+active+TRY+is+found+after+throwing+an+exception,+then+an+unhandled
exception+message+is+printed+to+stderr,+all+processing+is+terminated+within+the
current+CMD+shell,+and+control+is+returned+to+the+shell+command+line.

TRY+blocks+are+specified+using+macros.+Obviously+the+macros+must+be+defined
before+they+can+be+used.+The+TRY+macros+are+defined+using+the+following+CALL

++++call+exception+init

Besides+defining+@Try+and+@EndTry,+the+init+routine+also+explicitly+clears+any
residual+exception+that+may+have+been+left+by+prior+processing.

A+TRY/CATCH+block+is+structured+as+follows:

++++%25@Try%25
++++++REM+any+normal+code+goes+here
++++%25@EndTry%25
++++:@Catch
++++++REM+exception+handling+code+goes+here
++++:@EndCatch

-+Every+TRY+must+have+an+associated+CATCH.

-+TRY/CATCH+blocks+cannot+be+nested.

-+Any+script+or+:labeled+routine+that+uses+TRY/CATCH+must+have+at+least+one
++SETLOCAL+prior+to+the+appearance+of+the+first+TRY.

-+TRY/CATCH+blocks+use+labels,+so+they+should+not+be+placed+within+parentheses.
++It+can+be+done,+but+the+parentheses+block+is+broken+when+control+is+passed+to
++the+:@Catch+or+:@EndCatch+label,+and+the+code+becomes+difficult+to+interpret
++and+maintain.

-+Any+valid+code+can+be+used+within+a+TRY+or+CATCH+block,+including+CALL,+GOTO,
++:labels,+and+balanced+parentheses.+However,+GOTO+cannot+be+used+to+leave+a
++TRY+block.+GOTO+can+only+be+used+within+a+TRY+block+if+the+label+appears
++within+the+same+TRY+block.

-+GOTO+must+never+transfer+control+from+outside+TRY/CATCH+to+within+a+TRY+or
++CATCH+block.

-+CALL+should+not+be+used+to+call+a+label+within+a+TRY+or+CATCH+block.

-+CALLed+routines+containing+TRY/CATCH+must+have+labels+that+are+unique+within
++the+script.+This+is+generally+good+batch+programming+practice+anyway.
++It+is+OK+for+different+scripts+to+share+:label+names.

-+If+a+script+or+routine+recursively+CALLs+itself+and+contains+TRY/CATCH,+then
++it+must+not+throw+an+exception+until+after+execution+of+the+first+%25@Try%25

Exceptions+are+thrown+by+using

++++call+exception+throw++Code++Message++Location

where

++++Code+=+The+numeric+code+value+for+the+exception.

++++Message+=+A+description+of+the+exception.

++++Location+=+A+string+that+helps+identify+where+the+exception+occurred.
+++++++++++++++Any+value+may+be+used.+A+good+generic+value+is+"%25~f0[%25~0]",
+++++++++++++++which+expands+to+the+full+path+of+the+currently+executing
+++++++++++++++script,+followed+by+the+currently+executing+routine+name
+++++++++++++++within+square+brackets.

The+Message+and+Location+values+must+be+quoted+if+they+contain+spaces+or+poison
characters+like+&+%7C+<+>.+The+values+must+not+contain+additional+internal+quotes,
and+they+must+not+contain+a+caret+%5E.

The+following+variables+will+be+defined+for+use+by+the+CATCH+block:

++exception.Code++=+the+Code+value
++exception.Msg+++=+the+Message+value
++exception.Loc+++=+the+Location+value
++exception.Stack+=+traces+the+call+stack+from+the+CATCH+block+(or+command+line
++++++++++++++++++++if+not+caught),+all+the+way+to+the+exception.

If+the+exception+is+not+caught,+then+all+four+values+are+printed+as+part+of+the
"unhandled+exception"+message,+and+the+exception+variables+are+not+defined.

A+CATCH+block+should+always+do+ONE+of+the+following+at+the+end:

-+If+the+exception+has+been+handled+and+processing+can+continue,+then+clear+the
++exception+definition+by+using

++++call+exception+clear

++Clear+should+never+be+used+within+a+Try+block.

-+If+the+exception+has+not+been+fully+handled,+then+a+new+exception+should+be
++thrown+which+can+be+caught+by+a+higher+level+CATCH.+You+can+throw+a+new
++exception+using+the+normal+THROW,+which+will+clear+exception.Stack+and+any
++higher+CATCH+will+have+no+awareness+of+the+original+exception.

++Alternatively,+you+may+rethrow+an+exception+and+preserve+the+exeption+stack
++all+the+way+to+the+original+exception:

++++call+exception+rethrow++Code++Message++Location

++It+is+your+choice+as+to+whether+you+want+to+pass+the+original+Code+and/or
++Message+and/or+Location.+Either+way,+the+stack+will+preserve+all+exceptions
++if+rethrow+is+used.

++Rethrow+should+only+be+used+within+a+CATCH+block.


One+last+restriction+-+the+full+path+to+EXCEPTION.BAT+must+not+include+!+or+%5E.

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
:::DOCUMENTATION:::

EXCEPTION.BAT is a pure batch script utility that provides robust exception
handling within batch scripts. It enables code to be placed in TRY/CATCH blocks.
If no exception is thrown, then only code within the TRY block is executed.
If an exception is thrown, the batch CALL stack is popped repeatedly until it
reaches an active TRY block, at which point control is passed to the associated
CATCH block and normal processing resumes from that point. Code within a CATCH
block is ignored unless an exception is thrown.

An exception may be caught in a different script from where it was thrown.

If no active TRY is found after throwing an exception, then an unhandled
exception message is printed to stderr, all processing is terminated within the
current CMD shell, and control is returned to the shell command line.

TRY blocks are specified using macros. Obviously the macros must be defined
before they can be used. The TRY macros are defined using the following CALL

 call exception init

Besides defining @Try and @EndTry, the init routine also explicitly clears any
residual exception that may have been left by prior processing.

A TRY/CATCH block is structured as follows:

 %@Try%
 REM any normal code goes here
 %@EndTry%
 :@Catch
 REM exception handling code goes here
 :@EndCatch

- Every TRY must have an associated CATCH.

- TRY/CATCH blocks cannot be nested.

- Any script or :labeled routine that uses TRY/CATCH must have at least one
 SETLOCAL prior to the appearance of the first TRY.

- TRY/CATCH blocks use labels, so they should not be placed within parentheses.
 It can be done, but the parentheses block is broken when control is passed to
 the :@Catch or :@EndCatch label, and the code becomes difficult to interpret
 and maintain.

- Any valid code can be used within a TRY or CATCH block, including CALL, GOTO,
 :labels, and balanced parentheses. However, GOTO cannot be used to leave a
 TRY block. GOTO can only be used within a TRY block if the label appears
 within the same TRY block.

- GOTO must never transfer control from outside TRY/CATCH to within a TRY or
 CATCH block.

- CALL should not be used to call a label within a TRY or CATCH block.

- CALLed routines containing TRY/CATCH must have labels that are unique within
 the script. This is generally good batch programming practice anyway.
 It is OK for different scripts to share :label names.

- If a script or routine recursively CALLs itself and contains TRY/CATCH, then
 it must not throw an exception until after execution of the first %@Try%

Exceptions are thrown by using

 call exception throw Code Message Location

where

 Code = The numeric code value for the exception.

 Message = A description of the exception.

 Location = A string that helps identify where the exception occurred.
 Any value may be used. A good generic value is "%~f0[%~0]",
 which expands to the full path of the currently executing
 script, followed by the currently executing routine name
 within square brackets.

The Message and Location values must be quoted if they contain spaces or poison
characters like &amp; | &lt; &gt;. The values must not contain additional internal quotes,
and they must not contain a caret ^.

The following variables will be defined for use by the CATCH block:

 exception.Code = the Code value
 exception.Msg = the Message value
 exception.Loc = the Location value
 exception.Stack = traces the call stack from the CATCH block (or command line
 if not caught), all the way to the exception.

If the exception is not caught, then all four values are printed as part of the
"unhandled exception" message, and the exception variables are not defined.

A CATCH block should always do ONE of the following at the end:

- If the exception has been handled and processing can continue, then clear the
 exception definition by using

 call exception clear

 Clear should never be used within a Try block.

- If the exception has not been fully handled, then a new exception should be
 thrown which can be caught by a higher level CATCH. You can throw a new
 exception using the normal THROW, which will clear exception.Stack and any
 higher CATCH will have no awareness of the original exception.

 Alternatively, you may rethrow an exception and preserve the exeption stack
 all the way to the original exception:

 call exception rethrow Code Message Location

 It is your choice as to whether you want to pass the original Code and/or
 Message and/or Location. Either way, the stack will preserve all exceptions
 if rethrow is used.

 Rethrow should only be used within a CATCH block.


One last restriction - the full path to EXCEPTION.BAT must not include ! or ^.

EXCEPTION.BAT was designed and written by Dave Benham, with important

</code></pre>

I have a batch script with the statement as shown below:

<pre><code>for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE 2^&gt;NUL`) do if '.%%i.'=='.LocalDateTime.' set TIME=%%j
set TIME=%TIME:~0,12%
</code></pre>

But once I executed it returned an error which I couldnt understand first. Then got to know the error was because of missing the wbem in path env variable. This bat file is located in a central repository so that anyone can execute this. So, need to let the user know the reason if this error strikes again in their local machine.

I dont think there is a try catch statement in Batch. Also, known about ErrorLevel. But I am not sure how this can be implemented..Can anyone support me in this regard..
