General Question Converting to Orbiter (Universal) Time

[Columbia42]

How do you convert normal time to the universal time that Orbiter uses?

See this Wikipedia article on time zones: [ame]http://en.wikipedia.org/wiki/Time_zones[/ame]

Also, have a look inside the "Utils" folder of your Orbiter installation for an application called "Date", which can convert to and from the MJD format Orbiter uses.

So when it says UT in Orbiter, is that the same as GMT?

Yes.

UT=UTC=GMT=Zulu Time.

Many names for the same time zone...

 

[tblaxland]

UT=UTC=GMT=Zulu Time.

:nono: Those things are only very approximately the same and can be different by more than 60 seconds.

UTC=Zulu time
UT there is no such thing, but you can make a choice from several ways of measuring "universal time": http://en.wikipedia.org/wiki/Universal_Time#Versions
GMT=mean solar time=UT1
Orbiter time=TDB [ame="http://en.wikipedia.org/wiki/Barycentric_Dynamical_Time"]Barycentric Dynamical Time - Wikipedia, the free encyclopedia[/ame]


And for a more detailed discussion of it: Does Orbiter know what time it is? :facts:

opps! I never realised that there was so much more to it. Thanks for the correction Tblaxland!
