If we want to keep the selected dive "close" to where it was before an operation (whether a delete, or a reload, or something like that), then the most intuitive thing to do appears to be to select either the same dive again (if it still exists), or one very close to it in time. This helper allows us to identify the dive in the current dive list that is closest to the given time. We do this in the C code to ensure that we look at all dives in the dive_table - based on the id that is returned the UI can then figure out where this dive is currently shown.
