 Description  « Hide
Second Life is a global service. Its intrinsic "time zone" – so-called SLT, Second Life Time – should be a global, standard time that is already in universal use. It should be a time zone that doesn't change twice a year based on regional practices at a particular Linden Lab office. (Nor at the whim of the U.S. Congress, too, like PDT Daylight Saving Time). It should use a time zone that is already globally understood as a reference, and is already broadly used in Internet applications.

PROPOSED: change the entire Second Life service over to use UTC (Coordinated Universal Time) as the standard SLT "time of day".

For you nitpickers: For SL purposes, GMT would be close enough! Use of am/pm (rather than 24hr time) would continue.

The SL Viewer would then show the "Second Life Time" and date as HH:MM am/pm UTC (rather than PST/PDT depending on time of year). All events would be scheduled and shown in UTC. Essentially all service features now shown in PST/PDT would be shown instead in UTC.

This wouldn't require any changes in scripting. llGetWallclock() would still be defined as returning the time shown in the SL viewer. The wiki commentary on it would require amendment to note the reference to UTC rather than PST/PDT.

Why? (1) To avoid having SLT change twice a year on a schedule that means nothing to many (over half?) of SL's residents; (2) To improve coordination between residents by employing a universally-understood global time reference; (3) to enhance the international scope of Second Life by moving beyond a historical but now pointless regionalization.

When? The perfect time to make this transition is coming up: March 9, 2008 at 2am PST. That is the moment that Second Life Time is going to change anyway – from PST to PDT. Instead of 'springing forward' to 3am PDT, Second Life could then wind forward to 10am UTC and continue on from there. (Event schedulers already need to take this into account, as do residents - it would simply be bigger jump, one last time.)

(Whether the viewer itself would need to be updated to properly mark the time zone abbreviation, I don't know – but if so, that could be implemented at any earlier point, really.)

=== March 10, 2008 update ===
OK, missed the window of opportunity this time – shoot for November 2, 2008 ?

=== January 1, 2009 update ===
Hmmm, perhaps March 8, 2009 then. That's the next PST-to-PDT transition.

Comment [ Yes, moving to UTC would be great.

But there are lots of other things to do to make time more easy to manipulate for everyone.

First would be to drop American AM/PM convention and use 24-hours clock (what is called in the USA "military time"). Here (Europe) we are not used that much to 12-hours time. As if converting from PDT/PST were not hard enough, we have to figure out what the displayed time really means, and add 12 hours if it's the Pacific afternoon. Needless to say that I'm completly unable to tell if 12:23 AM is midday and 23 minutes (12:23 military) or midnight and 23 minutes (00:23 military).

For those who prefer AM/PM display, it could be an option in the settings.

The other pain in the neck is the date format. MM/DD/YYYY is completly illogical and leads to strange sorts in the group windows, for example. ISO format is both logical and international: YYYY-MM-DD.
