从单元中获取持续时间

from datetime import timedelta

# 创建一个持续时间对象
duration = timedelta(hours=2, minutes=30)

# 获取持续时间的总秒数
total_seconds = duration.total_seconds()
print(f"Total seconds: {total_seconds}")

# 持续时间的加减运算
new_duration = duration + timedelta(hours=1)
print(f"New duration: {new_duration}")

from datetime import datetime, timedelta
import zoneinfo

# 创建一个带有时区信息的持续时间
start_time = datetime.now(zoneinfo.ZoneInfo("UTC"))
end_time = start_time + timedelta(hours=2)
print(f"Duration in UTC: {end_time - start_time}")

from decimal import Decimal
from datetime import timedelta

# 使用Decimal提高精度
seconds = Decimal('3661.123456')
duration = timedelta(seconds=seconds)
print(f"Duration with high precision: {duration}")
