Editing availability dates while using timezones in mexico shift the date by an hour
This behavior has been resolved and deployed to the production environment as of 4/6/23.
When a creating user has their time zone set to Mexico City, Mazatlan, Guadalajara or Monterrey the date picker when editing an assignments availability dates will adjust the time provided to be an hour sooner than you entered if you type it in manually.
Using the drop-downs in the date picker do not cause this behavior to occur.
This behavior only occurs during the date range which used to be Mexico's daylight savings time (First April Sunday - Last Sunday in October)
Instead it should not adjust the time you entered to be incorrect when typing it manually.
No workaround exists at this time.
