Windows 2008 R2 Task Scheduler behavior with Fall daylight savings time clock fall-back

I have a task scheduled to run every minute in the task scheduler and my server is configured for daylight savings time.  When the clock falls back and repeats 1:00 am - 2:00 am this Sunday morning (11/3) will my task run every minute in the second 1:00 am - 2:00 am?  Inquiring minds want to know...
Thanks!

This is correct. It should run again as the time has actually changed. This counts for an additional hour during that day so that day actually has 25 hours instead of 24. This is also the reverse when the clocks go ahead we have 23 hours that day as we lose an hour.

So, to put a fine point on it, if my task runs at the first 1:59 am, then is scheduled to run again at 2:00 am, but the second after 1:59:59am is 1:00 am (again) and never hits the 2:00 am schedule run time, will the task scheduler run this scheduled task 1:00 am (the second 1:00 am of the day!) or will it not run until it is actually 2:00 am officially?

Thanks!

If your task run every minute it will run regardless of being 1am again or 2 am. Same goes for if the clocks were set ahead.
