+ * This routine converts time as follows.  The epoch is 0000  Jan  1
+ * 1970  GMT.   The  argument  time  is  in seconds since then.  The
+ * localtime(t) entry returns a pointer to an array containing:
+ *
+ *		  seconds (0-59)
+ *		  minutes (0-59)
+ *		  hours (0-23)
+ *		  day of month (1-31)
+ *		  month (0-11)
+ *		  year
+ *		  weekday (0-6, Sun is 0)
+ *		  day of the year
+ *		  daylight savings flag
+ *
+ * The routine corrects for daylight saving time and  will  work  in
+ * any  time  zone provided "timezone" is adjusted to the difference
+ * between Greenwich and local standard time (measured in seconds).
