+## @brief Convert seconds since the Epoch into a date and time
+## @details \fBob_touch_t_gmtime\fP() converts the number of non-leap seconds
+##          elapsed since the Epoch into date and time in UTC formatted for the
+##          \fB-t\fP option of the \fBtouch\fP utility according to POSIX.  It
+##          is similar to the C function \fBgmtime\fP except that it returns a
+##          formatted string instead of a structure.
+## @operand timep req The number of non-leap seconds elapsed since the Epoch.
+## @return Returns 0.
+## @stdout Prints the date and time in UTC formatted for the \fBtouch\fP
+##         utility's \fB-t\fP option.
+## @pure yes This function has no side effects.
