This definition makes it sound like it already takes into account the time zone offset. I'm late with that but here is my experience with dates and times. In a compagny when you have a client/server application, never use the date and time of a user's computer, in case of you have to store a date in a bill or a time in a log, for example. The settings of each computer has always different. Be confident in the server only. So if it is already difficult to manage time in the same country, in a same firm, it could be result to a real nightmare to manage time for differents users all over the world. I think the best is to trust an outside server which always give you the same time for everyone. Webservices for example allow you to retrive back the universal time. -- -Zryip TheSlug- wish you the best! 8) http://www.aslugontheroad.co.cc ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Re: The seconds and time zones
Yes. The seconds returns the number of seconds since Jan 1, 1970. And this is in GMT, or standard universal time. So any computer anywhere will always read the same number of seconds, provided their own time is correct. With that you can perform identical calculations as needed. craig Newman ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Jacques Hausser (who is not Jacque) wrote: But I can nevertheless say that I did set my computer (Mac OS X) to different time zones and the seconds didn't change accordingly... they seem trustable within a computer. The engine's internal clock is initialized when the engine starts up, so if you quit before you change your time zone the seconds will be reliable for comparisons across time zones. Here's a quick test I just did to verify this: At 7:01AM PST I got these values: Seconds: 1264518037 Internet Date: Tue, 26 Jan 2010 07:01:02 -0800 Then I quit Rev, opened my System Control Panel, changed my location to Brisbane AU, restarted Rev, and got these: Seconds: 1264518145 Internet Date: Wed, 27 Jan 2010 01:02:09 +1000 While the difference in global time is several hours, the difference in the seconds is merely 108, roughly the amount of time I spent quitting and changing my system's location. FWIW, I also tried this without quitting Rev in between, and apparently it does not update the time zone until you restart. So it appears the seconds are indeed useful for comparing times and dates across time zones, provided the time zone does not change while the engine is running. Personally, I prefer the Internet date format because it's human-readable. It also works at the same level of granularity (seconds) but carries the additional benefit of storing the time zone it was acquired in. The latter may not be useful for many apps, but I have one case where I need to know where people are in addition to when they perform a given action, and having the GMT offset embedded in the string helps me narrow that down. There is an unfortunate implication with this: because the engine needs to be restarted to update the GMT offset of its internal clock, this means that automatic changes to time zones like moving from PST to PDT will be ignored by the engine.

Anyone know if there's an RQCC request for that? My guess for the better solution is not to rely on a user's computer settings but find the time-server.com ping solution that works best for you and your clients. This would capture the daylight savings change regardless of the user's computer setting. The usual cautions with this are -1- Europe does not alway change the same week as the US -2- Each county in the US gets to decide whether to change time, and in which direction. eg. Indiana in the USA, some counties match Chicago, others Cincinnati, OH and others choose not to change at all. I used to live in a county that never changed its clock. It was a farming community that did not care to change. I haven't done the digging, but I did use the atomic clock server in a project about 4 years ago.

It all depends what you want :-) The seconds translates to a date time that depends on the time zone settings of the computer doing the conversion, so the same number will translate differently around the world. This may be what you need, but it is not always useful. I used to operate a series of kiosks in multiple time zones across Australia. They would send their reports back with time stamps. If I had used seconds, then the times would have been altered by the time they got to me, but I needed to know the times as they were at the kiosk. e.g. if a kiosk in Western Australia has a problem at 4 pm, when this gets to me, it gets translated to 6 pm. It was at 6 pm my time, but if I have to ring up someone on site, I need to tell them that the problem was at 4, not 6. So for me, using the seconds was not useful. The internet date is one alternative, but it doesn't account for daylight savings. I ended up using my own time stamp routines, with an AppleScript routine for working out daylight savings. To avoid all these issues, there is an enhancement request in the Rev QA http://quality.runrev.com/qacenter/show_bug.cgi?id=4949 asking for the universal seconds which would be a number of seconds that was not affected in any way by the time zone of the converting computer.
