 /*
 **  CONVTIME -- convert time
 **

+**     Takes a time as an ascii string with a trailing character
+**     giving units:
+**       s -- seconds
+**       m -- minutes
+**       h -- hours
+**       d -- days (default)
+**       w -- weeks
+**     For example, "3d12h" is three and a half days.
+**

 **     Parameters:
 **             p -- pointer to ascii time.
 **     Parameters:
 **             p -- pointer to ascii time.

+**             units -- default units if none specified.

 **
 **     Returns:
 **             time in seconds.
