Timezone for CronWorkflow not working for all expected zones

[endzyme]

Summary

Timezone settings for CronWorkflows don't appear to work for all expected timezones. I have set a timezone of Europe/Dublin and the controller does not actually start the job. There are some log messages that it is processing the job but nothing appears to start. When I changed to America/New_York or Europe/Paris it appears to work. I have also tested with Etc/GMT-1 and Europe/Amsterdam and same results, no worky.

Diagnostics

What version of Argo Workflows are you running?
v3.0.1

I will provide logs if needed.

It did, but I'll try to spin something up this coming week to provide proof. I saw your note on the related Dockerfile change. It's likely related but I haven't fully dug into why some timezones would work and others would not.
