Yes, a great help. You confirmed what I expected...I just did not want to be heading in the wrong direction. Which leads to another question: based on the output of zdump, it looks like rules not strictly included in a zone line are included if the first rule does not match the time at which the rules are used. Another example may help (with psuedo-syntax): Zone Test ... +1:00..........Until 17:00 1-Mar-2000u RuleSet1.....Until 17:00 1-Oct-2000u +2:00..........Until 17:00 1-Feb-2001u RuleSet2.....Until MAX Rule RuleSet1 1999-Only +3:00 Jan Rule RuleSet1 2000-Only +4:00 Aug Rule RuleSet2 2001-Max +5:00 Apr My understanding of this is that prior to 17:00 1-Mar-2000u, the zone will be +1:00, then after 1-Mar-2000 it will be +3:00, using the rule from 1999...then in 1-Aug it will jump to +4:00 and on 1-Oct-2000u it will swap to +2:00 and will remain there until 1-Apr-2001, since no rule in RuleSet2 applies until then. But, if we had a new rule: Rule RuleSet2 1997-Only +6:00 Oct Then at 1-Feb-2001u it would jump to +7:00. Again, I'm asking this to confirm my understanding is correct...it *seems* to be the way it behaves. Thanks again for your help...
