The simplest way that I found to convert between different time zones using only Java 8 APIs.
ZonedDateTime targetDate = ZonedDateTime
.parse("2016-11-20T11:00:00-05:00")
.withZoneSameInstant(ZoneId.of("America/Argentina/Buenos_Aires"));
| Original date | 2016-11-20T11:00:00-05:00 |
| America/Argentina/Buenos_Aires | 2016-11-20T13:00:00-03:00 |
| America/Sao_Paulo | 2016-11-20T14:00:00-02:00 |
Do you have a simpler way? Please comment here. 🙂
