Support for WEBSITE_TIME_ZONE in Linux consumption

[balag0]

This needs to have a higher priority. The provided workaround, which is scheduling everything in UTC, doesn't work for all scenarios - or I am missing an obvious solution for this.

or example, there is no way to have the function run every 3 hours between 9am-6pm every work day. The translated UTC schedule would be:

0 0 16,19,22,1 * * 1,2,3,4,5

But this will run once Sunday, and miss one run on Friday:

@balag0 Is it only for Consumption plan? I see user reported it for Linux Premium or App Service plan also. https://stackoverflow.com/questions/64316818/time-zone-issue-python-function-app-on-azure

[balag0]

Yes, this issue is specific to consumption plans only.

Hi, any updates on it? Looks like I just got this issue.

[NvHeijningen]

Hi, got the same problem here. Cant find a solution. Any updates?

[balag0]

@NvHeijningen @rodchenkov yes, this is still a limitation and we don't have an ETA yet. Are you able to workaround this in the meantime?

[pedrojunqueira]

Some issue here. Set up WEBSITE_TIME_ZONE configuration and still running on UTC tz

@balag0 this has been open since 2019 with no suggested work arounds. @paxos gave an example of which there seems to be no work around. Will this ever be fixed? Please advise.

[balag0]

Thanks for the ping.. I have opened an internal WI for prioritization. Will update here once we have a plan.

In the meantime, one possible (hacky) workaround, set the frequency greater than required timer frequency. Write code in the function code to check time and either do work or silently exit based on the current time in required timezone.

Ex: To run every 3 hours between 9am-6pm every work day

Configure the trigger to fire once an hour every day. In function code, get current time in utc, check if it is time to run the function , then either silently return or run the actual function logic. Understand its not ideal, but this might help unblock while the feature is coming online.
