DescriptionSometimes it can be useful to get the build date/time of a program/lib

I like this

because it can be very easily be converted to an integer. An integer is interesting because then you can compare build date/time and then have an update system

I would like this too, for generating header files with build date strings, version numbers based on release dates, etc, so I figured I'd just implement it. The result is in cmTimeCommand.zip, which I've just uploaded.

This 'time' command takes a variable name, and optionally a format specifier (as defined in http://www.cplusplus.com/reference/ctime/strftime/ [^]). The default is "%Y-%m-%d %H:%M:%S", which happens to be the format the OP requested. Examples:

time(my_iso_date) // 2013-04-15 16:36:05
time(version_number "%Y.%m") // 2013.04
time(build_date "%B %d, %Y") // April 15, 2013
time(my_time "%H:%M") // 16:35

Note that I have tested this by hand, but I'm not sure how you would add a test for this feature to the regression test set, as it will produce different output every time.

It seems this ticket can be closed with the new STRING(TIMESTAMP ...) feature in 2.8.11.
