PAWN SACRIFICE - Fact Check

In Pawn Sacrifice, it is shown that in a match, Bobby Fischer arrives a little late, then adjust all his pieces and gives his move at the 59th second...he would have lost in case he would have failed to give a move before the 1 minute mark.

I have read quite a bit about Bobby Fischer but I had never heard of this. So is it a true fact or has it been shown to enthrall the people watching the movie?

In case this is a true fact, any citations would be of much help to me.

Thanks.

There was a previous thread about this but I can't find it now.  If I recall correctly, Fisher did once (or more) show up late for a match and then dither a bit before moving, but it wasn't the same match (or even the same tournament?) as shown in the film.
