by Paul Holland Sept. 5, 2017

Sept. 5, 2017

Last update was in March (2017b). Last year there were many updates (10?). Does this mean (1) the database has stabilised; or (2) it is no longer actively maintained? Just curious :-D Cheers, Paul E: paul(a)holland.name

by Magnus Bengtsson Aug. 28, 2017

Aug. 28, 2017

IATA has sent out the following message: " Please be advised of the following 2017/18 DST dates for Fiji. Please amend the entry for Fiji in Appendix F of your SSIM MAR17 issue to reflect the following: Country Time Standard - - - DST Start - - - - - - DST End - - - DST Name Zone Variation Time Date Time Date Variation Fiji FJ +1200 1400 04NOV17 1400 13JAN18 +1300 " The end date (13JAN18) does not seem to conform to the current rule in tzdata2017b. I can't find any information about this on http://www.fiji.gov.fj Does anyone have any more information? /Magnus Bengtsson

Madras Observatory reports [RE: Fixed typos]

It seems unlikely that the Madras Observatory was making weather reports. I imagine the author intended to write "astronomical" measurements. However, since it is written as a direct quote the mistake should be left as is, possibly with [sic]? > > â¬Ice Karma >

Hi, I’ve created some tzdata syntax highlighting rules for the Sublime Text editor: https://packagecontrol.io/packages/zoneinfo <https://packagecontrol.io/packages/zoneinfo> I have no idea if anyone other than me uses that particular text editor for looking at tzdata files. But I thought I’d mention it just in case it’s useful to someone. Cheers, Gil
