Definitely not another Y2K, but it still was interesting. Here is what I noticed:
One personal note, both of my children were born on DLS weekends (both spring and fall). In fact, if my son was born 5 minutes later, they would have had to indicate which 1:00 AM he was actually born on. This was because there were 2 "1 AM" times that night (the fall). It was a little confusing because the nurses were updating all of the clocks beginning at midnight.
