import datetime

DATETIME_FORMAT = "%Y-%m-%d %H:%M:%S"
TIME_FORMAT = "%H:%M:%S"

#当前毫秒数
def curMilis():
 return int(time.time() * 1000)

#当前秒数
def curSeconds():
 return int(time.time())

#当前日期 格式%Y-%m-%d %H:%M:%S
def curDatetime():
 return datetime.datetime.strftime(datetime.datetime.now(),DATETIME_FORMAT)

#当前日期 格式%Y-%m-%d
def curDate():
 return datetime.date.today()

#当前时间 格式%Y-%m-%d
def curTime():
 return time.strftime(TIME_FORMAT)

#秒转日期
def secondsToDatetime(seconds):
 return time.strftime(DATETIME_FORMAT,time.localtime(seconds))

#毫秒转日期
def milisToDatetime(milix):
 return time.strftime(DATETIME_FORMAT,time.localtime(milix//1000))

#日期转毫秒
def datetimeToMilis(datetimestr):
 strf = time.strptime(datetimestr,DATETIME_FORMAT)
 return int(time.mktime(strf)) * 1000

#日期转秒
def datetimeToSeconds(datetimestr):

 return int(time.mktime(strf))

#当前年
def curYear():
 return datetime.datetime.now().year
#当前月
def curMonth():
 return datetime.datetime.now().month

#当前日
def curDay():
 return datetime.datetime.now().day

#当前时
def curHour():
 return datetime.datetime.now().hour

#当前分
def curMinute():
 return datetime.datetime.now().minute

#当前秒
def curSecond():
 return datetime.datetime.now().second

#星期几
def curWeek():
 return datetime.datetime.now().weekday()

#几天前的时间
def nowDaysAgo(days):
 daysAgoTime = datetime.datetime.now() - datetime.timedelta(days = days)
 return time.strftime(DATETIME_FORMAT,daysAgoTime.timetuple())

#几天后的时间
def nowDaysAfter(days):
 daysAgoTime = datetime.datetime.now() + datetime.timedelta(days = days)
 return time.strftime(DATETIME_FORMAT,daysAgoTime.timetuple())

#某个日期几天前的时间
def dtimeDaysAgo(dtimestr,days):
 daysAgoTime = datetime.datetime.strptime(dtimestr,DATETIME_FORMAT) - datetime.timedelta(days = days)
 return time.strftime(DATETIME_FORMAT,daysAgoTime.timetuple())

#某个日期几天前的时间
def dtimeDaysAfter(dtimestr,days):
 daysAgoTime = datetime.datetime.strptime(dtimestr,DATETIME_FORMAT) + datetime.timedelta(days = days)
 return time.strftime(DATETIME_FORMAT,daysAgoTime.timetuple())


secondStamp = curSeconds()
print("当前秒:",secondStamp)
milisStamp = curMilis()
print("当前毫秒:",milisStamp)

curdTime = curDatetime()
print("当前时间:",curdTime)
curDate = curDate()
print("当前日期:",curDate)
curT = curTime()
print("当前时刻:",curT)


stdtime = secondsToDatetime(secondStamp)
print("秒转时间:",stdtime)
mtdtime = milisToDatetime(milisStamp)
print("毫秒转时间:",mtdtime)
dtimetm = datetimeToMilis(mtdtime)
print("时间转毫秒:",dtimetm)
dtimets = datetimeToSeconds(mtdtime)
print("时间转秒:",dtimets)

year = curYear()
print("年:",year)
month = curMonth()
print("月:",month)
day = curDay()
print("日:",day)
hour = curHour()
print("时:",hour)
minute = curMinute()
print("分:",minute)
second = curSecond()
print("秒:",second)
week = curWeek()
print("星期:",week)

输出结果如下:


当前秒: 1518341913
当前毫秒: 1518341913403
当前时间: 2018-02-11 17:38:33
当前日期: 2018-02-11
当前时刻: 17:38:33
秒转时间: 2018-02-11 17:38:33
毫秒转时间: 2018-02-11 17:38:33
时间转毫秒: 1518341913000
