Random thought with no logical basis:

What if it’s the WoL themselves that cause time-locking. Thus far, the time locks we’ve observed so far only really happen once we cross over. Sure, probably coincidence…but you know what they say: one time a fluke, two a coincidence, three a pattern. We’re so far 2 for 2.

I only say 2 because I’m not sure about time on the 13th.

My money says time would sync as soon as the WoL gets inside, and there simply wouldn’t be a 30 year gap.
