The previous changes introduced incorrect timezone mappings for European regions. After investigating Windows timezone IDs used by Azure Data Factory:

Reverted changes:

  • North Europe (Ireland): W. Europe Standard TimeGMT Standard Time
  • UK South/West: Greenwich Mean TimeGMT Standard Time

Rationale:

  • Ireland and UK observe the same timezone (UTC+0/UTC+1 with DST)
  • GMT Standard Time is the correct Windows timezone ID for these regions
  • Greenwich Mean Time is not a valid Windows timezone ID
  • W. Europe Standard Time is for Central European Time (France, Germany, Netherlands), not Ireland

The original dev branch mappings were already correct. No timezone changes are needed.

Pull request overview

This PR reverts incorrect timezone mappings for European Azure regions in the FinOps hub managed exports module. The previous changes had incorrectly mapped Ireland and UK regions to invalid or wrong Windows timezone IDs. These timezone values are used by Azure Data Factory triggers for scheduling exports, and incorrect values can cause trigger failures.

Changes:

  • Corrected North Europe (Ireland) timezone from W. Europe Standard Time (Central European Time) to GMT Standard Time (UK/Ireland time)
  • Fixed UK South and UK West timezones from invalid Greenwich Mean Time to valid GMT Standard Time
