[Opensim-users] Correcting Metaverse Time

Tue Jan 20 14:53:57 UTC 2009

Well, maybe I am having trouble getting it, Stefan.

A few days ago, there were several multi-hour, heated discussions about how the timezones of different servers would make events and scripts malfunction.

Personally, I have been using UTC since the 1970's and GMT before that in communicating around this rock, so I dont get the flap and just use UTC/GMT, but it seems an important subject to others.

 Also, I believe we could just add local server time and current UTC ('metaverse time') to something like the 'about' box text, if people want to make sure.

As I understand it,

all times shown to users could and should be specified with timezone. The client does this, and there should be no problem converting from UTC to PST/PDT in the protocol endpoints if the client would need us to.

In regards to scripts, lsl still have a fairly good number of functions separating 'server time'/'pst' and 'gmt'/'utc';

llGetDate uses UTC
llGetWallclock returns the server time.
llGetGMTclock gets GMT, which essentially is UTC

I might just be naive, but I don't see the problem with UTC. Could we have a problem scenario detailed out?

Best regards,

Same for me, Robert.  Google Calendar works the same way. I just choose my time-zone.  Why not have the viewer show UTC and the local time of the user, just to help the user be able to see the Universal Grid Time at a glance?  All grid serverscould keep their time set by a reliable ntp server and passed on to the viewer/client.

Also, in the future, the viewer could very likely simply be a web browser, but I don't want to get too far off topic.

Hmm, any meeting or event that I have attended on this planet is generally
formatted in the timezone of the host venue. Anyone attending just has to
deal with it. What about each simulator uses the timezone of whatever the
admin chooses and each viewer simply runs in the timezone of the user's
computer? Scripts could therefore depend on that model and adjust themselves
accordingly. What about a toggle or on/off tick in the viewer? Would it even
need one?

Remember, 2-5 years from now hopefully we will not be depending on the SL
viewer as a stop-gap but instead be using the strengths of our own.
