Which components should take precedence if converting to an updated ruleset?

E.G. https://www.rfc-editor.org/rfc/rfc5545#section-3.8.5.3 (Internet Calendar) still has the issue of events not tied to the time a 'normal' human might expect if rules change.

Lunch service 11am to 3pm Weekdays, 11 to 2pm Weekends

How would that dynamically map to changes in the timezones that might be mandated by the law but reflect the correct event times in a scheduling system? Spreadsheet systems developed the $ prefix for cell addresses as a shorthand to lock that in when adjusting the relative offsets in copy and paste / duplicate operations.
