The ICCCM document states that "Clients must not use CurrentTime
in  the  ``time'' field." when using XSetInputFocus.  So I made
my code use the time from the WM TAKE FOCUS message, but this
doesn't work at all with mwm or olwm (it does work sometimes with
twm).  I changed my code to use CurrentTime instead and it now
seems to work fine.  Does anyone know why this is happening?
Will I have other problems from using CurrentTime?

From the ICCCM:
|> 4.2.7.  Input Focus
...
|> Once a client satisfies these conditions,  it  may  transfer
|> the  focus to another of its windows using the SetInputFocus
|> request:
|> 
|> SetInputFocus
|>         focus:  WINDOW or PointerRoot or None
|>         revert-to:      {Parent, PointerRoot, None}
|>         time:   TIMESTAMP or CurrentTime
|> 
|>      Convention: Clients using SetInputFocus  must  set
|>      the  ``time''  field to the timestamp of the event
|>      that caused them to make the attempt.   Note  that
|>      this cannot be a FocusIn event,  since they do not
|>      have timestamps,  and that clients may acquire the
|>      focus   without   a   corresponding   EnterNotify.
