The result is a String, which is a formatted date and time, as specified by the {format} string. The given {time} is used, or the current time if no time is given. The accepted {format} depends on your system, thus this is not portable! See the manual page of the C function strftime() for the format. The maximum length of the result is 80 characters. See also localtime(), getftime() and strptime(). The language can be changed with the :language command. Examples:

:echo strftime("%c")             Sun Apr 27 11:49:23 1997
:echo strftime("%Y %b %d %X")    1997 Apr 27 11:53:25
:echo strftime("%y%m%d %T")      970427 11:53:55
:echo strftime("%H:%M")          11:55
:echo strftime("%c", getftime("file.c"))
                                 Show mod time of file.c.

Not available on all systems. To check use:

:if exists("*strftime")

Can also be used as a method:

GetFormat()->strftime()
