We need these both to use the same timezone and be scheduled an hour apart across the entire calendar year.

| Resolved | BUG REPORT | bd808 | T404399 wmf/next branch cut job on releases-jenkins and systemd timer on deployment server times overlap |
Setting the branch cut job to 01:00 UTC and the build and deploy job to 02:00 UTC seems like a reasonable solution.
Currently that means the systemd timer is deploying yesterday's wmf/next and then an hour later cutting the nightly wmf/next. In October, this will happen at the same time.
@dancy did the 02:00Z change in https://gerrit.wikimedia.org/r/c/operations/puppet/+/1230952. I think that means that we just need to switch the timezone in https://releases-jenkins.wikimedia.org/job/MediaWiki%20branch%20and%20publish%20WMF%20single-version%20image/configure

Both jobs now use UTC for scheduling and have an hour between job starts:
Changing either/both to only fire Monday-Thursday is left as an exercise for the future when we work on deploying the containers.
