+.SH DESCRIPTION
+The functions
+.BR timelocal ()
+and
+.BR timegm ()
+are the inverses of
+.BR localtime (3)
+and
+.BR gmtime (3).
+Both functions take a broken-down time and convert it to calendar time
+(seconds since the Epoch, 1970-01-01 00:00:00 +0000, UTC).
+The difference between the two functions is that
+.BR timelocal ()
+takes the local timezone into account when doing the conversion, while
+.BR timegm ()
+takes the input value to be Coordinated Universal Time (UTC).
+.SH RETURN VALUE
+On success,
+these functions return the calendar time (seconds since the Epoch),
+expressed as a value of type
+.IR time_t .
+On error, they return the value
+.I (time_t)\ \-1
+and set
+.I errno
+to indicate the error.
+.SH ERRORS
+.TP
+.B EOVERFLOW
+The result cannot be represented.

+GNU, BSD.
+.P
+The
+.BR timelocal ()
+function is equivalent to the POSIX standard function
+.BR mktime (3).
+There is no reason to ever use it.
