Hello everyone, this is my first post in this forum.
In his free time playing with app inventor and noticed that it's hard to get time UTC/DST from the clock component.
I thought of this solution, it can work all over the world?
Thank you!

probably easier would be to use a parse procedure like in this example

Thank you, finally a new block has been added for this purpose.
It is no longer necessary to use parse.

To find the UTC, I found an easy solution by mistake:

I expected 00:00:00, but the 1 in front is because I live in UTC+1 I was told. I do not now what the value is if you live in UTC-6, but maybe it is easy to figure out.
Cheers, Ghica.

you also can use the pattern Z, for all patterns see here https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

Holy spaghetti, I looked for the solution to this problem for months and now ... :)
Thanks again Ghica and Taifun, I will apply one of the solutions as soon as possible in the new version of my app (EtnaLive!)
