class time.struct_time 定義


The type of the time value sequence returned by gmtime(), localtime(), and strptime(). It is an object with a named tuple interface: values can be accessed by index and by attribute name. The following values are present:


Index ?| Attribute ? Values
---------------------------------------------------------------------
0 ? | tm_year ? ?(for example, 1993)
1 ? | tm_mon ? ?range [1, 12]
2 ? | tm_mday ? ?range [1, 31]
3 ? | tm_hour ? ?range [0, 23]
4 ? | tm_min ? ?range [0, 59]
5 ? | tm_sec ? ?range [0, 61]; see (2) in strftime() description
6 ? | tm_wday ? ?range [0, 6], Monday is 0
7 ? | tm_yday ? ?range [1, 366]
8 ? | tm_isdst ? ?0, 1 or -1; see below
N/A ? | tm_zone ? ?abbreviation of timezone name
N/A ? | tm_gmtoff ? offset east of UTC in seconds
---------------------------------------------------------------------


time.time()
Return the time in seconds since the epoch as a floating point number


time.gmtime([secs]) 0時區的時間
Convert a time expressed in seconds since the epoch to a struct_time in UTC in which the dst flag is always zero. If secs is not provided or None, the current time as returned by time() is used. Fractions of a second are ignored.?


time.localtime([secs]) 本地時間
Like gmtime() but converts to local time. If secs is not provided or None, the current time as returned by time() is used. The dst flag is set to 1 when DST applies to the given time.


time.mktime(t) ?與localtime()的功能恰好相反
This is the inverse function of localtime()


time.sleep(secs)
Suspend execution for the given number of seconds


time.strftime(format[, t])
Convert a tuple or struct_time representing a time as returned by gmtime() or localtime() to a string as specified by the format argument. If t is not provided, the current time as returned by localtime() is used. format must be a string. ValueError is raised if any field in t is outside of the allowed range.
