Except for the confusing datasheet (it's sometimes referring its internal oscillator as external, and you have no idea which is which), I think this table will help. According to it - and if I parse it correctly - it's around 30 usecs. And since the timer won't start before the user presses a button, it's perfectly in limits. I mean, noone will be able to turn the device on and within 30 usecs press the button.
