python utc时间与本地时间转换

python utc时间与本地时间转换

 1、utc与本地时间互转

# python3.6

from datetime import datetime
from pytz import utc

# 本地时间
dt_loc = datetime.now()
# 本地时间转UTC时间
dt_utc = dt_loc.astimezone(utc)
# UTC时间转本地时间
dt_loc1 = dt_utc.astimezone()

# 字符串为UTC时间，需要调整到LOC时间，差值通过计算得到
utc_dt = datetime.strptime("2021-11-05 08:00:00", "%Y-%m-%d %H:%M:%S")
now_stamp = time.time()
loc = datetime.fromtimestamp(now_stamp)
utc = datetime.utcfromtimestamp(now_stamp)
utc_offset = loc - utc
loc_dt = utc_offset + utc_dt

2、日期与字符串互转

from datetime import datetime

# 字符串转时间
dt = datetime.strptime("2021-11-05 08:00:00", "%Y-%m-%d %H:%M:%S")
# 时间转字符串
dt_str = dt.strftime("%Y-%m-%d %H:%M:%S")
