This happens when the clocks "go back". The update here is to use the original timestamp offset as the tie-breaker when the local representation of the truncated time could be ambiguous. ## What changes are included in this PR? <!-- There is no need to duplicate the description in the issue here but it is sometimes worth providing a summary of the individual changes in this PR. --> ## Are these changes tested?
