Question about Vizard Expiration Timer Rate

[mizutani_jun]

Hi.
Just want to ask simple question.
What is the fastest vizard timer expiration rate?
I`m pretty sure vizard have fastest timer expiration rate but i dont know the exact value.
Of course i cant use command like below right?

viz.callback(viz.TIMER_EVENT,read_simulation)
viz.starttimer(0,0.000001,viz.FOREVER)

I want to make replay for simulation i did and i want to add function like fastforward or fastbackward so i thinking of using timer to make scene faster or slower.
But seems the rate that i took all the data is maybe close to the vizard fastest timer expiration rate so all the scene that i fastforward or fastbackward dont show too much difference.
Hope somebody can help.
Thanks.

A value of 0 will get you the fastest timer expiration. That's close to once every frame.

Can you describe it in value of second? [like 0.001sec]
I want to know the fastest timer expiration rate so i can decide the best sampling rate to save the data.
