Migrate from org.joda.time.DateTimeZone to Java Time
Joda-Time DateTimeZone migrates to java.time ZoneId or ZoneOffset.
ZoneId is the same concept, an identifier of a time-zone.
ZoneOffset is a new concept, an offset from UTC.
Beforeorg.joda.time.DateTimeZone forID = DateTimeZone.forID(zoneId); org.joda.time.DateTimeZone forOffsetHours = DateTimeZone.forOffsetHours(offsetHours);After
ZoneId forID = ZoneId.of(zoneId); ZoneOffset forOffsetHours = ZoneOffset.ofHours(offsetHours);
Note: the recipes for getName and getShortName do not map exactly to the ZoneId.getName method, this is deliberate. The Joda-Time getName and getShortName methods will return different names depending on whether the long argument(which represents an instant in time) is in daylight savings time or not. In java.time, the ZoneId getName method does not respect daylight savings time changes. In order to follow this original behaviour, we need to create a ZonedDateTime and format it using a DateTimeFormatter, this is what the recipes have been designed to do.

This may introduce further problem markers in the IDE, as the usage of this reference, may then use DateTimeZone methods that do not exist on java.time.ZoneId. Further sensei recipes are available to help migrate these invalid method names to java.time equivalents where possible. descriptionFile: descriptions/datetimezone.html tags: framework specific;java.time;Joda-Time;quality search: expression: type: org.joda.time.DateTimeZone referenceTo: name: UTC availableFixes: - name: Convert To java.time.ZoneOffset.UTC actions: - rewrite: to: java.time.ZoneOffset.UTC target: self
