我有一个Python datetime对象,我想将其转换为unix时间,或自1970 epoch以来的秒/毫秒。
我怎么做呢?

当前回答
很多答案在python2中不起作用,或者没有从datetime中保存毫秒。这对我很有用
def datetime_to_ms_epoch(dt):
microseconds = time.mktime(dt.timetuple()) * 1000000 + dt.microsecond
return int(round(microseconds / float(1000)))
其他回答
这是另一种形式的解决方案与规范化的时间对象:
def to_unix_time(timestamp):
epoch = datetime.datetime.utcfromtimestamp(0) # start of epoch time
my_time = datetime.datetime.strptime(timestamp, "%Y/%m/%d %H:%M:%S.%f") # plugin your time object
delta = my_time - epoch
return delta.total_seconds() * 1000.0
from datetime import datetime
from calendar import timegm
# Note: if you pass in a naive dttm object it's assumed to already be in UTC
def unix_time(dttm=None):
if dttm is None:
dttm = datetime.utcnow()
return timegm(dttm.utctimetuple())
print "Unix time now: %d" % unix_time()
print "Unix timestamp from an existing dttm: %d" % unix_time(datetime(2014, 12, 30, 12, 0))
一段熊猫代码:
import pandas
def to_millis(dt):
return int(pandas.to_datetime(dt).value / 1000000)
在我看来,最简单的方法是
import datetime
epoch = datetime.datetime.utcfromtimestamp(0)
def unix_time_millis(dt):
return (dt - epoch).total_seconds() * 1000.0
import time
seconds_since_epoch = time.mktime(your_datetime.timetuple()) * 1000
