Issue connecting to my devices during the Montreal daylight saving time transition period.

Can you try

bacnet = BAC0.lite()
bacnet.timehandler.set_timezone("America/Costa_Rica")

Thanks Christian,

I apologize if I wasn't clear before. I encounter the error when calling BAC0.lite() and cannot proceed to set the timezone.

Here are the steps I'm following to reproduce the error:

• I set my computer's time zone to either UTC or America/Costa_Rica (a timezone without daylight saving).
• I set my computer's clock to 2:15 am on March 10, 2024.
• I attempt to initialize BAC0 with bacnet = BAC0.lite().

I assume the failure occurs because, although my computer's time zone does not depend on daylight saving, initializing the library consider the America/Montreal zone, where that hour (2:15am 10March24) would not exist.

Is there a way to change the timezone before initializing the library, perhaps as a parameter at the start? Or could it possibly take the system's time zone?

If I change the initialization inside the library's code to America/Costa_Rica (inside TimeHandler class), the problem disappears, but I would prefer not to edit the library and instead make the change externally.

Thank you very much.

Can you test cloning the master branch and pip install it ? I just modified it to add the arg timezone

and use :

import BAC0
bacnet = BAC0.lite(timezone="America/Costa_Rica")

By the way, I've added that to the new async version that use bacpypes3 that you can try also. Look for branch Async

This will replace the actual version of BAC0 soon

Omg!, thanks Christian. this works perfect!
