Currently Mexico_City is not in DST, But with TZinfo gem we are getting time as per DST.

You need to update your time zone data.

The change to stop observing DST for America/Mexico_City was included in version 2022f of the IANA Time Zone Database.

TZInfo v1 and later can either use zoneinfo files from your system or the tzinfo-data gem as the source of the data. You can use TZInfo::DataSource.get to see what data source tzinfo is using.

If you're using the tzinfo-data gem, then check you're using version 1.2022.6 or later. If you're not using the tzinfo-data gem (using the system zoneinfo files), then check for an updated time zone data package for your operating system (or switch to the tzinfo-data gem by adding it to your Gemfile).
