The output of zdump tells me when there is a change in the rules for a timezone but it doesn't seem to tell me what the rules are. In other words, given a particular zoneinfo file, how can I determine the zone and rules that were used to create it?
The compiled zoneinfo file which zdump is reading does not maintain a record of what file was compiled to generate it, nor does it maintain a record of the rules used to generate the transitions that it contains. Your best bet is to download the latest tzdata files from elsie, check that the rule(s) of interest is correct in the appropriate file, and install the zic'ed version of the file if it looks good, overwriting any old zoneinfo file whose rules you are questioning. --Ken Pizzini
