Python时间戳的使用和相互转换

如a =

"2013-10-10 23:40:00"

,想改为 a =

"2013/10/10 23:40:00"

import time

timeStamp = 1381419600
timeArray = time.localtime(timeStamp)
otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)
otherStyletime == "2013-10-10 23:40:00"

    方法二:

import datetime
timeStamp = 1381419600
dateArray = datetime.datetime.utcfromtimestamp(timeStamp)
otherStyleTime = dateArray.strftime("%Y-%m-%d %H:%M:%S")
otherStyletime == "2013-10-10 23:40:00"

import time

# 获得当前时间时间戳
now = int(time.time())

# 转换为其他日期格式,如:"%Y-%m-%d %H:%M:%S"
timeArray = time.localtime(timeStamp)
otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)

import datetime

#获得当前时间
now = datetime.datetime.now()  #这是时间数组格式

#转换为指定的格式:
otherStyleTime = now.strftime("%Y-%m-%d %H:%M:%S")

import time
import datetime

# 先获得时间数组格式的日期
threeDayAgo = (datetime.datetime.now() - datetime.timedelta(days = 3))

# 转换为时间戳:
timeStamp = int(time.mktime(threeDayAgo.timetuple()))

# 转换为其他字符串格式:
otherStyleTime = threeDayAgo.strftime("%Y-%m-%d %H:%M:%S")

# 注:timedelta()的参数有:days,hours,seconds,microseconds

timeStamp = 1381419600

# 先转换为datetime
import datetime
import time
dateArray = datetime.datetime.utcfromtimestamp(timeStamp)
threeDayAgo = dateArray - datetime.timedelta(days = 3)

# 参考5,可以转换为其他的任意格式了
