On your checkride you need to time your hold to arrive over the fix w/i
about 1 minute of the specified time.


That relates to timed approaches from a holding fix, which is the only time
a crossing time will be specified. No specific tolerances on the time are
given anywhere that I know of. I wouldn't disagree with your "about one
minute", although nobody I know uses tolerances that large in training.
DPEs around here don't seem to specify a time.
