Adding the date of adoption of the Gregorian reform for a given region to the compiled time zone is of interest to the social studies (history, economics, political science) as well as geographers, environmentalists, trade and shipping historians, genealogists, etc.. The results could/should be packaged as a easily reference and useful document for users of this nature. They in turn might be able to provide inputs also. regards - Jake Knoppers -----Original Message----- From: Andrew Brown [mailto:atatat@atatdot.net] Sent: Tuesday, July 29, 2003 8:25 PM To: Oscar van Vlijmen Cc: TZ-list Subject: Re: epochs and the gregorian reform

while it's not strictly related, i've often found myself wondering if adding the date of the adoption of the gregorian reform for a given region to the compiled zone file might be of interest.

One of the places where information about the Julian -> Gregorian transition dates are kept is The Calendar FAQ: http://www.tondering.dk/

that's really neat, and i'll bookmark it. that said, informationally, it's approximately the same as the calendrical calculations book. while useful to know about, it's not really sufficient programmatically, since the data is still in "text" form and not easily accessible to your program. :) thanks again for the link. -- |-----< "CODE WARRIOR" >-----| codewarrior@daemon.org * "ah! i see you have the internet twofsonet@graffiti.com (Andrew Brown) that goes *ping*!" werdna@squooshy.com * "information is power -- share the wealth."
