做开发中难免时间类型之间的转换, 最近就发现前端js和后端django经常要用到这个转换, 其中jsDate.now()精确到毫秒,而Python中Datetime.datetime.now()是精确到微秒的。

try :

t = d.timetuple()
timeStamp = int (time.mktime(t))
timeStamp = float ( str (timeStamp) + str ( "%06d" % d.microsecond)) / 1000000
print timeStamp
return timeStamp
except ValueError as e:
print e

print timeStamp
return timeStamp
