1.获取当前时间的时间错
if __name__ == '__main__': t = time.time() print(t) # 原始时间数据 1575598311.9527097 print(int(t)) # 秒级时间戳 1575598311 print(int(round(t * 1000))) # 毫秒级时间戳 1575598311953 print(int(round(t * 1000000))) # 微秒级时间戳 1575598311952710
2.获取当前时间,包含格式
strftime:时间格式化,使用方式 time.strftime(format)
if __name__ == '__main__': dt = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S') #2019-12-06 10:13:52 dt_ms = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S.%f') # 含微秒的日期时间,来源 比特量化 2019-12-06 10:13:52.018611
3.将日期转为秒级时间戳
if __name__ == '__main__': dt = '2019-12-06 10:13:52' timearr = time.strptime(dt, "%Y-%m-%d %H:%M:%S");#转换为时间数组 print(timearr) #time.struct_time(tm_year=2019, tm_mon=12, tm_mday=6, tm_hour=10, tm_min=13, tm_sec=52, tm_wday=4, tm_yday=340, tm_isdst=-1) ts = int(time.mktime(timearr)) print(ts) #1575598432
4.将时间戳转换为时间
if __name__ == '__main__': ts = 1515774430 dt = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(ts)) print(dt) #2018-01-13 00:27:10
5.时间格式转换
用到了datetime
if __name__ == '__main__': dt = '12/02/2019 01:00:10' dt_new = datetime.datetime.strptime(dt, '%m/%d/%Y %H:%M:%S').strftime('%Y-%m-%d %H:%M:%S') print(dt_new) #2019-12-02 01:00:10
