Time.time ()

Returns the time as a floating-point number.

On Windows and most UNIX systems, the era is January 1, 1970 00:00:00 (UTC), and the leap second does not count toward the number of seconds since the epoch.

>>> time.time () 1508211081.817371>>> a = Time.time () >>> time.gmtime (a) Time.struct_time (tm _year=2017, tm_mon=10, tm_mday=17, tm_hour=3, tm_min=32, tm_sec=2, Tm_wday=1, tm_yday=290, tm_isdst=0)

You can use gmtime () to convert timestamps to a more friendly way

Time.gmtime ([second])

Converts the time in seconds from the epoch to the struct_time of UTC , where the DST flag is always zero.

If secs or none is not provided, the current time is returned using the date ().

>>> time.gmtime (0) time.struct_time (tm_year=1970, Tm_mon=1, Tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, Tm_wday =3, Tm_yday=1, tm_isdst=0) >>> time.gmtime () time.struct_time (tm_year=2017, tm_mon=10, tm_mday=17, Tm_hour=3, Tm_min=35, tm_sec=26, Tm_wday=1, tm_yday=290, tm_isdst=0)

Time.localtime ([second])

Like Gmtime (), but converted to local time . If secs or none is not provided, the current time is returned using the date ().

>>> Time.localtime (Time.struct_time) (tm_year=2017, tm_mon=10, tm_mday=17, tm_hour=11, tm_min=40, tm_sec=24, Tm_wday=1, tm_yday=290, tm_isdst=0)

Time.sleep (seconds)

Suspends execution of the calling thread. The parameter can be a floating-point number to indicate a more accurate sleep time.

Time.strftime (format [, T])

Converts the tuple or struct_time that represents the time returned by Gmtime () or localtime () to the string specified by the format parameter.

If T is not provided, the current time is returned using localtime ().

The format must be a string. If any of the fields in t exceed the allowable range, ValueError is raised.

>>> time.strftime ('%y-%m-%d ') ' 2017-10-17 '
