.desc begin
The &func functions convert the calendar time pointed to by
.arg timer
into a broken-down time, expressed as Coordinated Universal Time (UTC)
(formerly known as Greenwich Mean Time (GMT)).
.np
The function
.kw _gmtime
places the converted time in the
.kw tm
structure pointed to by
.arg tmbuf,
and the &func &function places the converted time in a static
structure that is re-used each time &func is called.
.im tzref
.desc end
.return begin
The &func functions return a pointer to a structure containing the
broken-down time.
