Mindful of folks with old compilers, it may be best to change the northamerica file to avoid use of 24:00, changing the "lastSat 24:00" references to "lastSun 0:00".
This would not be correct. For example, in 1932, the last Saturday in April was April 30, 1932 so the change to DST happened that night. Changing the entry to "lastSun 0:00" would cause the change to DST in 1932 to take place on Sunday, April 24, 1932 -- a week too early.
