 *
 * u2ltime converts "UNIX time" (seconds since 00:00 1 Jan. 1970 UTC) to
 * the "local" system time. If integer arguments are supplied, their
 * equivalent local times are supplied. If run without arguments, it
 * displays the current times.
 *
 * u2ltime was orignally written in anticipation of the billionth
 * UNIX second.
 *
 * u2ltime has been compiled and tested on:
 *  SunOS 5.[78]
 *  NetBSD 1.[45]
