减去日期值中的时间

from datetime import datetime, timedelta

date_string = "2022-10-20 09:30:00"
date = datetime.strptime(date_string, "%Y-%m-%d %H:%M:%S")
date_without_time = date.replace(hour=0, minute=0, second=0, microsecond=0)

print(date_without_time)

const dateTimeString = "2022-10-20T09:30:00";
const date = new Date(dateTimeString);
date.setHours(0, 0, 0, 0);

console.log(date.toISOString().split("T")[0]);

import java.time.LocalDate;
import java.time.LocalDateTime;

String dateTimeString = "2022-10-20T09:30:00";
LocalDateTime dateTime = LocalDateTime.parse(dateTimeString);
LocalDate dateWithoutTime = dateTime.toLocalDate();

System.out.println(dateWithoutTime);
