The actual results of the 2nd are obviously preferrable to the 1st... but I do note something squirrly going on with the hours in both (daylight savings time?) Indeed it is daylight savings. date has no cygwin-specific patches, but the brand new coreutils 5.90 has been released upstream that has some patches in date parsing. Once I can get that packaged, you may want to rerun your tests - if the bug is still present at that time, then report it upstream. - -- Life is short - so eat dessert first!
