We have code to enable and disable the RTC's UIE interrupt, as well as check whether it occurred and skip the first interrupt as it may be bogus. This is currently used as part of maintaining the correction file. In a later commit, we will need the same functionality for using the RTC as reference clock, so export the functions and give them descriptive names appropriate for globally visible functions.
