help

help(time.time)

Help on built-in function time in module time:

time(...)
    time() -> floating point number
    
    Return the current time in seconds since the Epoch.
    Fractions of a second may be present if the system clock provides them.

help(time.localtime)

Help on built-in function localtime in module time:

localtime(...)
    localtime([seconds]) -> (tm_year,tm_mon,tm_mday,tm_hour,tm_min,
                              tm_sec,tm_wday,tm_yday,tm_isdst)
    
    Convert seconds since the Epoch to a time tuple expressing local time.
    When 'seconds' is not passed in, convert the current time instead.

help(time.asctime)

Help on built-in function asctime in module time:

asctime(...)
    asctime([tuple]) -> string
    
    Convert a time tuple to a string, e.g. 'Sat Jun 06 16:26:11 1998'.
    When the time tuple is not present, current time as returned by localtime()
    is used.

help(time.strftime)

Help on built-in function strftime in module time:

strftime(...)
    strftime(format[, tuple]) -> string
    
    Convert a time tuple to a string according to a format specification.
    See the library reference manual for formatting codes. When the time tuple
    is not present, current time as returned by localtime() is used.
    
    Commonly used format codes:
    
    %Y  Year with century as a decimal number.
    %m  Month as a decimal number [01,12].
    %d  Day of the month as a decimal number [01,31].
    %H  Hour (24-hour clock) as a decimal number [00,23].
    %M  Minute as a decimal number [00,59].
    %S  Second as a decimal number [00,61].
    %z  Time zone offset from UTC.
    %a  Locale's abbreviated weekday name.
    %A  Locale's full weekday name.
    %b  Locale's abbreviated month name.
    %B  Locale's full month name.
    %c  Locale's appropriate date and time representation.
    %I  Hour (12-hour clock) as a decimal number [01,12].
    %p  Locale's equivalent of either AM or PM.
    
    Other codes may be available on your platform.  See documentation for
    the C library strftime function.
