Thanks for the warning.

The moral of the story is trust ri more than man, if you care about 
portability:

[~] ri strftime | grep '%[FT]'
[~] man strftime | grep '%[FT]'
Reformatting strftime(3), please wait...
        %F     Equivalent to %Y-%m-%d (the ISO 8601 date format). (C99)
               ing the seconds, see %T below.
        %T     The time in 24-hour notation (%H:%M:%S). (SU)
        %F conversion is in C99 and POSIX 1003.1-2001.
