After I learned where to look on this list, I looked there, and found some very nice advance work by the developers responsible for maintenance of tzdata. When one runs dpkg-reconfigure tzdata, one sees a list of continental region designations. At the bottom of the list is "Etc". If one selects that item, one is presented with a multitude of options that mostly begin with GMT- or GMT+. These are 'time zones' that are simple hourly offsets from GMT without local legal mandates. The senses of GMT- and GMT+ are the reverse of what I first guessed. These are better than Arizona for me. With the collapse of cranky conservativism, Arizona might take up daylight saving time, but GMT+7 should not change. It is the local time for the 105degrees west meridion. The list contains some synonyms: GMT GMT0 GMT+0 GMT-0 Greenwich UCT UTC Universal Zulu all seem to invoke the same interpretation of Unix time. GMT+12 and GMT-12 are there, and they are not the synonyms. They differ by one day in the date. This applies also to GMT-13 and GMT-14. They are not the same as GMT+11 and GMT+10. I guess that the developers responsible for maintenance of time-zone code that includes local-mandates/social-conventions, keep the code for these hourly offsets as a starting point for patching in new legal/local logic. I appreciate them giving it mnemonic names and making it available for general use, via the Etc designation. I am continually amazed by Debian. Every day in every way it gets better and better. -- Paul E Condon [email protected] -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
