I want to ask if --backupts needs to consider the time. For example, my system time is UTC time. If I want to back up the data from the early morning of June 14, 2023, should I specify --backupts as 2023-06-13 16:00:00 or 2023-06-14 00:00:00?

When using BR for backup, the --backupts parameter does not need to consider time zones. BR will convert it to a UTC timestamp and then use that timestamp for the backup. Therefore, no matter which time zone you run BR in, you do not need to consider time zone issues.
