Do you consume the Pagerduty API? Are you annoyed that the timezones they use aren't standard IANA timezone names used by pretty much every timezone library that builds on the Olson TZ database?
Yeah, me too.
I dug around and found a mapping, however it had a few inconsistencies. I've gone down the list and verified each one. Here's a JSON for you. Enjoy!
Diff of the zones I altered is below as well.
