Time Zones
Please Note: some of the time zones and abbreviations noted here, have been invented by contributors to various of my sources to accommodate language differences or local customs, or to just fill in a blank. Before using any of these zones or abbreviations, please verify them independently to be sure of their correctness. Just because they are here, doesn't mean they're correct!
Time zones are created by local decree and do not necessarily follow any international standard. Ostensibly, a village government can create their own time zone. To add to the confusion, historically Paris Mean Time (+00:09:05) has been the French equivalent to Greenwich Mean Time. Happily, France now acknowledges GMT but this goes to show you how politics can confuse and confound science.
DO NOT accept this list as valid. This has been collected from a variety of sources to present only what an abbreviation might mean, not to be an authoritative source. However, Arthur David Olsen maintains a comprehensive listing of time adjustments and zones for the Linux operating system. Please e-mail corrections to him at tz@elsie.nci.nih.gov and send me a copy so I can correct this list.

²The Time Zone Mailing List. This is not a web page and is for download only. Extract the files to view a continent by continent examination of time. It is intended to support Linux time and zone settings. In some instances a contributor has made up time zone abbreviations. They are "CVT – Cape Verde Time, AAT – Atlantic Africa Time, WAT – West Africa Time, CAT – Central Africa Time, EAT – East Africa Time, SMT – and, Seychelles and Mascarene Time." Please consider this in your usage.
