python如何获取更多时间戳精度
调度任务中常常要用到精确的时间,如果获取的13位时间戳不够准确的话,会造成数据的重复或者缺失
通常的不准确的13位时间戳的获取方式(秒*1000)
import timemillis = int(round(time.time() * 1000))
print millis
准确的13位时间戳获取(微妙/1000)
# -*- coding: utf-8 -*-
import datetime
import time

获取精确毫秒数时间戳、
"""
def get_seconds():
datetime_object = datetime.datetime.now()
now_timetuple = datetime_object.timetuple()
now_second = time.mktime(now_timetuple)
mow_millisecond = long(now_second*1000 + datetime_object.microsecond/1000)
print "timetuple-- "+ str(now_timetuple)
print "datimeobject-- " + str(datetime_object)
print "second-- " + str(now_second)
print "millisecond-- " + str(mow_millisecond)
if __name__ == "__main__":
get_seconds()
结果
timetuple-- time.struct_time(tm_year=2018, tm_mon=12, tm_mday=3, tm_hour=11, tm_min=55, tm_sec=6, tm_wday=0,tm_yday=337, tm_isdst=-1)
datimeobject-- 2018-12-03 11:55:06.254679
second-- 1543809306.0
millisecond-- 1543809306254
