At 2AM EDT Oct 30, 2005, it will become 1AM EST Oct 30, 2005. This shift will take us from GMT -4 to GMT -5.
As always, hang onto your hats, as I have no idea how the time change will affect the graphing in GrabPERF. My theory is that there should be double measurements for the 1 AM hour, and the hourly rollup will fail, as there will already be an entry for the time period.
I could write an exception for this twice yearly foobar, but let’s just say this update is scraping the bottom of the GrabPERF punch-list.
At least I don’t have this problem.
