It is clear why it is so, but the general behaviour still seems not proper. This Etc/UTC to UTC time converter is an online time. Time difference between Etc/UTC and UTC is 0:0 hours ie., UTC time is always 0:0 hours ahead of Etc/UTC. Etc/UTC is a UTC +00:00 timezone offset where as UTC is a UTC 0:0 timezone offset. ZonedDateTime zonedDateTimeUtc0 = now.withZoneSameInstant(utc0Zone) ĪssertEquals(om(zonedDateTimeUtc.toInstant()), om(zonedDateTimeUtc0.toInstant())) ĪssertEquals(0, pareTo(zonedDateTimeUtc0)) ĪssertEquals(zonedDateTimeUtc,zonedDateTimeUtc0) Enter any time in Etc/UTC and find the corresponding asia/kabul time using this Time Calculator.
by the tz code) allows for TZZonedDateTime zonedDateTimeUtc = now.withZoneSameInstant(utcZone) Zone Etc/GMT 0 - GMT Zone Etc/UTC 0 - UTC Zone Etc/UCT 0 - UCT The. Otherwise this is a bug in documentation, because it is not expectable that these two dates build in the same timezone would be different.įrom the other hand when using "UTC" and "UTC+0" timezones dates become equal: The technical reason for this behaviour are clear, but it seems to be bug in the design of implementation compareTo and equals methods. We need sudo privileges to change this file because this is a system-wide configuration. Then we register (store) the copy module's results in a variable called timezone for later use.
#Etc utc time zone plus
However they aren't due to the reasons described above. As you can see, we're just adding one line: Etc/UTC plus a return (newline character) which gets placed in the file /etc/timezone. ZoneDateTimeEtcUtc.equals(zoneDateTimeUtc) should be true. ZonedDateTime zoneDateTimeUtc = now.withZoneSameInstant(utcZone) ZonedDateTime zoneDateTimeEtcUtc = now.withZoneSameInstant(etcUtcZone) These all breaks a quite expectable logic, that these two ZonedDateTimes (zoneDateTimeEtcUtc and zoneDateTimeUtc): However, because ZomeId equality is based on ZoneId:Īnd pareTo is based on comparing zone ids:Ĭmp = getZone().getId().compareTo(other.getZone().getId()) Another way to check the time zone is to view the path the symlink points to using the ls command: ls -l /etc/localtime lrwxrwxrwx 1 root root 27 Dec 3 16:29 /etc/localtime -> /usr/share/zoneinfo/Etc/UTC Changing the Time Zone in Linux Before changing the time zone, you’ll need to find out the long name of the time zone you want to use.
In fact these two objects has the same ZoneRules, what is correct. Will be equal in all comparison related operations.
ZoneId etcUtcZone = ZoneId.of("Etc/UTC") So it is expectable, that the two ZoneId's created as: Thats whats done if a search for a Tcl time zone definition in. TimeZones are historical - UTC offset and DST rules may change depending. Java HotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)Īccording to TZ specification, "Etc/UTC" represents "UTC", so these two time zones are essentially the same: TimeZone represents a regions offset from UTC and its daylight savings time rules.
