automatic timezone for Cancun Mexico

For somereason we dont fully understand, the governor of Quintana Roo (state were Cancun is) in Mexico changed the timezone for us. For decades we have been in -06:00 GMT with daylight savings time changes.

Since Feb 1st. The whole state changed to -05:00 GMT without daylight saving time. For owners of Apple gadgets we have to change from Cancun time, to Miami time, then (when daylight savings started) to Dallas time to try to catch with the correct time.

Can somebody change the record at the time servers for the new setting?

Thanks!
