by Paul Eggert May 25, 2015

May 25, 2015

It's March Madness time for daylight-saving rule changes. Here's a proposed change to the tz database to keep up with the latest political development, which affects time stamps starting March 29: * Latvia and Lithuania will not observe DST, starting this year.

Question concerning Daylight Saving Time in the Bahamas
by John Griswold June 23, 2002

June 23, 2002

Hi,, I have been reading the Daylight Saving Time tables (at http://stat.tamu.edu/ftp/usr/share/lib/zoneinfo/northamerica) that are on the internet and saw your email address. I am doing some research on the Bahamas. Am I correct in my reading of the tables for North America that the Bahamas were not observing Daylight Saving Time in 1959? It seems that the table is saying that the Bahamas did not observe it until 1964. Any help in this matter would be greatly appreciated. I have also sent this message to Paul Eggert, but I don't know if he is still working on this Daylight Saving Time table project. Thank you, John Griswold

FW: Time zone equality?
by Olson, Arthur David (NCI) June 21, 2002

Kerry Kimbrough is not on the time zone mailing list; direct replies appropriately. --ado -----Original Message----- From: Kerry Kimbrough [mailto:kkimbrough@clearcommerce.com] Sent: Friday, June 21, 2002 10:57 AM To: 'tz(a)elsie.nci.nih.gov' Subject: Time zone equality? Help! Can someone explain the algorithm for TimeZone::operator==? That is, how do you know if two time zones are the same or different? I'm motivated by a UI design issue that's become hot around here. We allow users to select a time zone from a list. In our case, the list come from the ICU package, which I understand uses the same list as the Olsen package. Trouble is, this list is huge and bewildering, with a great deal of apparent redundancy. For example, there are 37 different time zones listed at GMT-04:00. This makes for a usability issue, as it becomes hard to search and confidently select the correct choice. And many are convinced that the long is just wrong because they can see a much shorter one used in Windows. We want to generate a shorter list, but we're also reluctant to just throw out legitimate choices. If two time zones are equivalent, then it's OK to drop one from the list. But how can you tell? How does Windows do it? ---- Regards, Kerry
