Ok, I've just produced a new build (It'll be at http://www.espruino.com/binaries/git/commits/b4edf13c51c825ca8ed032d7e31dec7a2759a20f within the hour). Could you try that? I've just removed all the RTC code changes that were there for the F1, so all being well it should behave exactly the same as 1v87.
