关于时间

import time
import datetime
t = datetime.datetime.now()
time_now =t.strftime('%Y-%m-%d %H:%M:%S')    # 获取现在时间 如：2022-09-19 17:33:41

time_before = (t-datetime.timedelta(minutes=10)).strftime("%Y-%m-%d %H:%M:%S")    # 获取十分钟前的时间
stime = int(time.mktime(time.strptime(time_now,'%Y-%m-%d %H:%M:%S')))    # 获取时间戳秒级时间戳
etime = int(time.mktime(time.strptime(time_before,'%Y-%m-%d %H:%M:%S')))    # 获取十分钟前的秒级时间戳

t = time.time()
time_s = int(round(t * 1000))    # 获取毫秒级时间戳

times = time.time()
gmtimes = time.strftime("%Y-%m-%d %H:%M:%S", time.gmtime(times))    # 获取格林威治时间
