Time Format ISO8601

[j_dodek]

Hi,

I have to format a time in ISO8601

It should look like: YYYY-MM-DDThh:mm:ssTZD (1997-07-16T19:20:30+01:00)

I am able to format it to UTC without the TZD (Time Zone Designator)

In Germany there is +01.00 

but now we have summertime +1h so it is equal GMT +00:00

Is there a way to get the TZD in TestStand

Hi Jürgen,

maybe this helps:

Juergen,

Another reason why you should use LabVIEW rather than that C "what's it stuff"

Hi Ray,

It seems in this case the LabView Example( Thanks Andreas! ) will not fit all my needs.

In my Post i did a misstake! About adding the summertime 

I Said if you push 1+  Then GMT(+1) + Summer(+1) = GMT(+0) Seems i have to go back to primary school

a learn some mathematic fundmentals.

I need a simple function that gives my local time in against UTC.

Example: 

If you are in Greenwich, New York, Berlin(Winter), Berlin(Summer) and get your local time at THIS moment

You will get:

Greenwich       10:20:30+00:00

NY                   05:20:30-05:00

Berlin(Winter)  11:20:30+01:00

Berlin(Sum)     12:20:30+02:00

So getting the local time is very simple Teststand Time() will do it!

But now i need to determine should i add +01:00 or +02:00

Jürgen,

so you don't want to get the local time, but you need to read out the difference to UTC?

Hi Andreas,

No, I want to get my current local time and the deviation to UTC

Here in Germany it is +1:00 (Winter) +2:00(Summer)

I need an API that should give me +1:00 / +2:00

or if i am in NY -5:00

See this link on chapter 5.3.4.2

The mentioned example shows how to read the bias using Windows' kernel32.dll. The function is GetTimeZoneInformation.

Will this VI help?

I found a bug in the VI for timezones with a positive offset from GMT. The community link is correct, but the vi link points to the old version...

More developement work has been done here and shared as open source project. A very comprehensive set of time zone libraries. You can also find the package via JKI VI Package manager by searching for "Epoch"
