request: timezone support in Cron

[kyranet]

Is there an existing issue or pull request for this?

• I have searched the existing issues and pull requests

Feature description

Currently, Cron supports only UTC, however, it could be adapted to support various timezones, even local time.

Desired solution

Implement a way to define the timezone offset, this can be a function so we can calculate it in case a timezone's offset changes due to DST.

In the future, we can add support for Temporal.TimeZone.

Alternatives considered

N/a.
