A very big mistake of the clock. The clock is 2 minutes behind for a night!
Give the clock back to the seller?
Like any tool of it's type and price range, it's not always going to be 100% accurate in the myriad different conditions people use it.
It's easy to simply sync the time manually using GPS.
Or better still, assign time syncing to a hot-key.
Imho, it's certainly not an issue which would necessitate return of the device.
Some Garmin watches are notorious for their clock inaccuracy, but, gee, 2 minutes per day? Unless a hard reset helps to resolve the issue, it's broken. Return it. With some luck you'll get a much more accurate unit.
And I though my FR735XT that goes slow 6 seconds per day was bad.
