Here is a suggestion:
Instructions:
1. Rename "myCardName" & "myStackName" with your card and stack names
2. make a field called "runningTimecode"
3. then, just call the handler "updateTC" once
It updates 10 times per second.
handlers:
------------
on updateTC
put convertTime(round(the currenttime of tPlayer()/the timescale
of tPlayer())) into fld "runningTimecode"
if ",updateTC," is not in the pendingmessages then send
"updateTC" to me in 100 milliseconds
end updateTC
function convertTime
put the currenttime of tPlayer() into this_time
put the timescale of tPlayer() into movie_scale
put this_time div movie_scale into total_seconds
put (this_time mod movie_scale) into partial_seconds
put ("." & partial_seconds) * 10 into tenths
put total_seconds div 3600 into tHours
put (total_seconds - (tHours * 3600)) div 60 into tMinutes
put (total_seconds - (tMinutes * 60) - (tHours * 3600)) div 1
into tSeconds
set the numberformat to "##"
if tHours <> 0 then
return tHours & ":" & tMinutes & ":" & tSeconds & ":" & tenths
else
return tHours & ":" & tMinutes & ":" & tSeconds & ":" & tenths
end IF
end convertTime
function tPlayer
return "player" && q("Player") && "of cd" && q("myCardName") &&
"of stack" && q("myStackName")
end tPlayer
function q a
return quote & a & quote
end q

I'm working for the first time with players. I'd like my stack,
which will
be used to work with video, to include include a running timer
display (in
the format minutes:seconds.tenths of seconds). I know to do the
currentTime/timeScale calculation and then go from there to display in
minutes:seconds.tenths format.
What is the most reasonable condition to trap for to perform the
calculation
frequently enough so the display is timely and responsive but
doesn't demand
unnecessarily frequent recalculation of the time?
Thanks in advance. I'm really a novice in this area.
