Tag: Day does not have a post BSP return between the specified GPO timestamp

Datetime.datetime.now () returns the current datetime date type

>>> D=datetime.datetime.now () >>> ddatetime.datetime (2018, 2, +, +, A, A, 372222) >>> D.year2018>>> d.month2>>> d.timetuple () time.struct_time (tm_year=2018, tm_mon=2, tm_mday=17, tm_ Hour=17, tm_min=41, tm_sec=49, tm_wday=5, tm_yday=48, Tm_isdst=-1) >>> D.timestamp () #转换为时间戳1518860509.372222 >>> d.replace (year=1997,month=9,day=21) #时间替换datetime. DateTime (1997, 9, 21, 17, 41, 49, 372222)

Datetime.date.fromtimestamp () converts a timestamp to a datetime date type

>>> Datetime.date.fromtimestamp (1518860509.372222) datetime.date (2018, 2, 17)

Datetime.timedelta: Represents a time interval, that is, the length between two points in time

>>> Datetime.datetime.now () datetime.datetime (2018, 2, +, +, A, 336825) >>> Datetime.datetime.now ()-Datetime.timedelta (3) #如果没有指定, default is 3 days datetime.datetime (2018, 2, +, +, +, 980665) >> > Datetime.datetime.now ()-Datetime.timedelta (days=3) #减去3天datetime. DateTime (2018, 2, 9, 23454) >>& Gt Datetime.datetime.now () + Datetime.timedelta (hours=3) #加3个小时datetime. DateTime (2018, 2, 17, 20, 50, 19, 688480
