parseDateTime split is using default time format if not passed via timeSettings

splitDateTime uses the format from the effective timeSettings. When called by parseDateTimeInternal/parseDateTime this is not necessarily the same as the timeFormat passed via the argument (so one must actually pass it both as the argument and in timeSettings to get the correct/expected results). This shouldn't be necessary.
