What time does the rollover occur? Is it based on UTC, or what?

I assume UT1: https://www.oc.nps.edu/oc2902w/gps/timsys.html https://en.wikipedia.org/wiki/Universal_Time#Versions

Which is roughly UTC, give or take multiple seconds.

GPS atomic time rolled over approximately midnight UTC this Sunday morning, but ignoring leap seconds. GPS is 18 seconds ahead of UTC and 19 seconds behind atomic TAI. http://leapsecond.com/java/gpsclock.htm
