Trying to understand retention policies

For example if you have done snapshots at:

2001-01-01 14:01 - not hourly because 14:30 was the last snapshot of this hour
2001-01-01 14:30 - hourly-2
2001-01-01 15:01 - not hourly because 15:55 was the last snapshot of this hour
2001-01-01 15:02 - not hourly because 15:55 was the last snapshot of this hour
2001-01-01 15:40 - not hourly because 15:55 was the last snapshot of this hour
2001-01-01 15:50 - not hourly because 15:55 was the last snapshot of this hour
2001-01-01 15:55 - hourly-1

This doesn’t work on my machine:

  2023-07-28 06:46:16 +07 pins:initial-backup
  2023-07-30 04:34:14 +07 (daily-7) <-- This is not the latest time in the day
  2023-07-30 09:53:45 +07 (latest-10)
  2023-07-30 23:53:15 +07 (latest-9,daily-6,weekly-2) <-- Second snapshot of the day
  2023-08-01 01:35:07 +07 (latest-8,daily-5,monthly-2) <-- Not the latest time again
  2023-08-01 15:48:48 +07 (latest-7)
  2023-08-02 06:11:23 +07 (latest-6,daily-4) <-- Not the latest time
  2023-08-02 15:35:20 +07 (latest-5)
  2023-08-02 21:52:25 +07 (latest-4,daily-3) <-- Two daily snapshots again
  2023-08-03 15:15:50 +07 (latest-3,hourly-3)
  2023-08-04 05:12:52 +07 (latest-2,hourly-2,daily-2)
  2023-08-05 01:00:57 +07 (latest-1,hourly-1,daily-1,weekly-1,monthly-1,annual-1)

All snapshots were taken in the same timezone.

Does anyone know what’s going on here?

Is Kopia using the timezone of the SFTP storage?
