**  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.
**
**	Returns:
**		time in seconds.
**
**	Side Effects:
**		none.
