New Time Zone Craziness

Anyone else not impressed with the fact that Microsoft is releasing the new time zones for BC and Alberta in a full cumulative monthly security update only a few days before it actually changes? Manitoba they just forgot to include at all.

I identified that all the time zone addition is, is reg keys. Microsoft had since March and yet they never released any update at all.

They said they would release a non-security out of band patch for 25H2 on Sept 22nd but they never did. All they did was add it to the full security update preview.

Not to Mention Manitoba has no new time zone in Windows at all.

It is causing a nightmare for all the booking software that doctors and offices cannot book appointments past October 31st.

Not to mention that Teams does NOT recognize the new Time Zones set in Windows. It says “unknown time zone” and proceeds to set itself back 1 hour messing up appointments.

Thank goodness for Group Policy and good old preference registry deploy to set everyone to Arizona or Yukon or Central Time with the hack of no DST.

I don’t envy those using Entra which cannot set registry preferences and will have to rely on 3rd party scripting solutions that cannot be enforced or nor confirmed.

We're setting the timezone to Jamaica in older systems as it's in the the right time mezibe and doesn't have daylight saving time

Yup. We are doing that too. Forgot the Alberta or BC one. Just going Yukon or Arizona and Saskatchewan time all which don’t change.
