The Zone Abbreviations as compiled by Rodden-McDonough and by Taeger are for the most part similar. The only major discrepancies are:
- Rodden calls the meridian 0 degrees East/ 0 degrees West by the name GMT (Greenwich Mean Time) inasmuch as astronomical calculations for our planet originate from Greenwich observatory. Taeger calls by the name WET (Western European Time). GMT or UT is used by Taeger not as a time zone but as a common basic standard for astronomical calculations related to Greenwich.
- We may also note that the meridian 15 degrees East is called both MET (Middle European Time) and CET (Central European Time) by different astrologers.
- For all the time zones, Rodden uses the distinction of DT (Daylight Time) or WT (War Time) when appropriate.
- Taeger uses the distinction of adding a /S to designate the distinction of both DT and WT.
We recognize that certain standards are in common usage in different parts of the world (such as GMT or WET, and MET or CET) and consider that an educated astrologer is capable of integrating standards that are flexible enough to include alternate zone names, providing that those alternates are not excessive.
With first-hand knowledge of your own zone, you are able to contribute to the education of all of us by correcting any zone flaws. In all the reference material on hand, there are inconsistencies. Until someone takes on the major project of updating all this material, there is some speculation on various time zones. Let us work together to resolve some of these questions. (I, for one did not know that Germany ever used Double Daylight until Hans Taeger pointed it out. Does anyone know if Guam ever used Daylight Time?)
