How do I get the date/time?

[Robotengineer]

I am trying to do timestamps for my plug-in, KerbLog. I have tried KSPUtil.KerbinYear, KSPutil.KerbinDay, etc. I have tried the KSPUtil.GetDateFromUT methods, but I don't know how to get UT or even if it is what I am looking for.

Hmmm. Interesting, never seen those methods before.

The current gametime I've always used is Planatarium.GetUniversalTime(), that returns a double that is seconds since game start.

However, I've never had to make that human readable, I'm not sure how you would go about converting it. Maybe KSPUtil.GetDateFromUI( Planetarium.GetUniversalTime()); ?

I will try that, hopefully it will work.

That works, and I believe FlightGLobals.ActiveVessel.missionTime will work for elapsed mission time timestamps.

Perhaps I'm misunderstanding something obvious here but when I try to use KSPUtil.GetDateFromUT(Planetarium.GetUniversalTime()); I'm getting an error: "The best overloaded method match for 'KSPUtil.GetDateFromUT(int)' has some invalid arguments" -> "Argument 1: cannot convert from 'double' to 'int'"

My code looks like this:

double currentUniversalTime = KSPUtil.GetDateFromUT(Planetarium.GetUniversalTime());

Planetarium.GetUniversalTime() returns a Double, so you would have to cast/convert it as an Int for the GetDateFromUT function.

Although what GetDateFromUT is gonna return I dont know as Planetarium.GetUniversalTime() is the current Universal Time. If you are looking for something that converts UT to year and day I can share a timelibrary I worked on recently that I think is ready. But cant link it till I get home

Cool, so I'll just mess about with converting the function then. Also, if you can upload the timelibrary I'll definitely check it out. Thanks.

I have it in place in a dev branch of my TWP mod. The two files you need are:

https://github.com/TriggerAu/TransferWindowPlanner/blob/feature/timelibrary/TransferWindowPlanner/FrameworkExt/KSPDateTime.cs

https://github.com/TriggerAu/TransferWindowPlanner/blob/feature/timelibrary/TransferWindowPlanner/FrameworkExt/KSPTimeSpan.cs

Just put these in your project and add using KSPPluginFramework; and you shoudl have them accessible

Basically these are KSP versions of the c# datetime and timespan structs. So some simple examples are:

KSPDateTime dt = new KSPDateTime(301.123);

This will give you a Datetime of year 1, Day 1, Hour 0, Minute 5, Second 1, millisecond 123 - each attribute (Hour, Day, etc is a property you can read)

You can do add/deletes/compares like the DateTime ones too

dt = dt.AddDays(3);
dt = dt.AddHours(-5)

gives you dt of Year 1, Day 2, Hour 1, Minute 5, Second 1, millisceond 123

You can also create the datetie/timespans the other way round

KSPDateTime dt2 = new KSPDateTime(3,3);

Gives you year 3, day 3 and the UT will match - it reads the game settings to know if you are in 6hour or 24 hour days

Lastly you can also use Earth Time for RSS, and the usual datetime string formats

KSPDateStructure.SetEarthCalendar();
KSPDateTime dt3 = new KSPDateTime(301.123);
Debug.WriteLine(dt3.ToString("yyyy-MM-dd HH:mm:ss")

This will output 1951-01-01 00:05:01 - as RSS Start date is 1 jan 1951

Yessssss.

If Trigger's gonna publicly post that, I'm gonna publicly thank him!

Thank you very much Trigger

No Probs, When I finally get all the 0.90 tidied away i'll add more detail to the pluginframework proper like
