Convert string time with offset from UTC to UTC unix

Question

如何将带有偏移量的字符串时间从 UTC 转换为 UTC unix？

Answer 1

Code:

from datetime import datetime, timezone, timedelta


def strtime_to_unix(str_time: str, utc_offset: int, format: str = '%d.%m.%Y %H:%M') -> int:
    return int(datetime.strptime(str_time, format).replace(
        tzinfo=timezone(timedelta(seconds=utc_offset * 60 * 60))).timestamp())


str_time = '27.06.2022 12:35'

print(strtime_to_unix(str_time, 0))  # 12:35 UTC -> 1656333300
print(strtime_to_unix(str_time, -4))  # 16:35 UTC -> 1656347700
print(strtime_to_unix(str_time, 3))  # 09:35 UTC -> 1656322500

Output:

1656333300
1656347700
1656322500
