System.DateTime on MASTER not working correctly with timezones

[DierkDroth]

I can't provide a Deck.NET sample due to this bug: https://forums.bridge.net/forum/brid...r-offset-issue

Here the code to reproduce (note: I have set my local PC to Casablanca timezone for that test):

new DateTime(636318720000000000).ToString()

Expected output:

"01.06.2017 00:00:00"

Actual output:

"05/31/2017 23:00:00"

Pls disregard any formatting issues. The relevant part is the actual date/time value. Thanks

Here is another example the timezone handling in System.DateTime is completely screwed up:

new DateTime(636318720000000000L).ToLocalTime().Subtract(new DateTime(636318720000000000L).ToUniversalTime()).TotalHours.ToString()

If I set my PC to Moscow timezone I get an output of "6", which is wrong, since Moscow is not 6 hours ahead of UTC.

Good Morning DierkDroth have you tried using https://dev.deck.net/ - this is the current build.

https://dev.deck.net/151f5e40c7c1b2a695758f376db9ad0c It seems the top example is fixed.

Just wondering if you would like to test the second issue on dev.deck.net :)

Poking

 
 new DateTime(636318720000000000L).ToLocalTime().Subtract(new DateTime(636318720000000000L).ToUniversalTime()).TotalHours.ToString();

... into Deck.NET does not show any result at all.

Not sure what other is causing that now...

DierkDroth – Please share a link to a Deck.NET (dev) sample demonstrating how to reproduce.

What exactly are you expecting that sample to do?

[DierkDroth]

Pls try this link and set your PC local timezone to Moscow time before:
https://deck.net/ede5fe2463590c81b370728ea0a328e8

The output of "6" is incorrect, since it does not correctly reflect the offset between Moscow timezone and UTC, which is 3 hours.

[geoffrey.mcgill]

I'm expecting an output in the 'Result' column ... there is none at this point.

There is no result in the Result panel because you do not output anything to the Document or Bridge.Console.

From what I can tell, the sample you provided appears to be working as expected.

samuelgrahame curious: how to you manage to switch between 'official' Deck.NET 15.7.0 and the version you had been using which runs on a particular commit?

[samuelgrahame]

im not sure how to run non master branches, but if you clone and build there project you can build your project using that, i just found out about dev deck website, it runs a branch from there git.

[DierkDroth]

Understand

geoffrey.mcgill Leonid I just checked: dev.deck.net exhibits the same issue. Is this an acknowledged bug or am I doing something wrong?
