Exdates returning UTC date without TZID offset

[Lawton Spelliscy]

Reporting an issue

I am finding that an rruleset with exclusion dates returns dates without the offset of the timezone within the rruleset.

Example

var r = rrule.rrulestr('DTSTART;TZID=America/New_York:20231114T220000\nRRULE:UNTIL=20231118T220000;INTERVAL=1;FREQ=DAILY\nEXDATE;TZID=America/New_York:20231116T220000');
r.all()
/**
output : [
  2023-11-15T03:00:00.000Z,
  2023-11-16T03:00:00.000Z,
  2023-11-18T03:00:00.000Z,
  2023-11-19T03:00:00.000Z
] ✅ 
*/
r.exdates()
// expected: [ 2023-11-17T03:00:00.000Z ]

// actual: [ 2023-11-16T22:00:00.000Z ]

rrules version: 2.7.2

operating system: macOS 14

timezone: EST

Is this expected behaviour? It seems strange that exdates are not consistent with the instances. Thanks!
