| The bridge stores time as a timestamp + the zone ID. Unfortunately, this representation is ambiguous for some timestamps, in particular when clocks are set back due to switching daylight saving time. For instance "2011-10-30 2:50:00 CET" may point to either "2011-10-30 2:50:00+01:00" or "2011-10-30 2:50:00+02:00".
A safer string representation would be something like what's done in java.time.format.DateTimeFormatter.ISO_ZONED_DATE_TIME, where both the offset and the zone ID are explicitly stored (something like "2011-10-30 2:50:00+01:00[CET]") Some strategy will have to be chosen to handle previously stored ZonedDateTimes, since we'll have to change the storing format and cannot assume that users will reindex everything. Pull request with test case coming. |
