commit a3d876c64fef75af9a81174ebfb99bfd95b9d32e
Author: Evan Rusackas <[email protected]>
AuthorDate: Mon Jan 26 21:58:34 2026 -0800

    fix(tests): update time-comparison test expectations for timezone-mock 1.4.0
    
    timezone-mock 1.4.0 changed the fromLocal algorithm to follow the
    EcmaScript specification for resolving local times to UTC timestamps.
    This affects Etc/GMT-2 timezone test cases where the local-to-UTC
    conversion now produces different results. Updated all Etc/GMT-2
    expected values in getTimeOffset.test.ts and parseDttmToDate.test.ts
    to match the new behavior.
