MAKETIME(<C time string>)
 Makes an invalid time string valid.
 Returns <expC> time string valid in format and contents.

 <expC> time string is in the format "HH:MM:SS",
 the same as returned by the TIME() function.

 Valid times are in the range "00:00:00" to "23:59:59",
 or 12:00:00 a.m. (midnight) to 11:59:59 p.m. (one second before midnight).

 Takes a "best guess" in cases where the valid time is not obvious.

 * User-entry time string may be invalid
 m_timestr = "  :  :  "
 @...SAY "Enter time as time string:";
     GET m_timestr PICTURE "##:##:##"
 READ

 * Make into valid time
 IF .NOT. ISTSTIME(m_timestr)
    m_timestr = MAKETIME(m_timestr)
 ENDIF
