How to format a ZonedDateTime to a String?
I want to convert a ZonedDateTime
to a String
in the format of ("dd/MM/yyyy - hh:mm")
. I know this is possible in Joda-Time other types, just using their toString("dd/MM/yyyy - hh:mm")
....But this doesn't work with ZonedDateTime.toString()
.
How can I format a ZonedDateTime
to a String
?
EDIT:
I tried to print the time in another timezone and the result appears to be the same always:
ZonedDateTime date = ZonedDateTime.now();
ZoneId la = ZoneId.of("America/Los_Angeles");
ZonedDateTime date2 = date.of(date.toLocalDateTime(), la);
// 24/02/2017 - 04:53
System.out.println(DateTimeFormatter.ofPattern("dd/MM/yyyy - hh:mm").format(date));
// same result as the previous one
// 24/02/2017 - 04:53
System.out.println(DateTimeFormatter.ofPattern("dd/MM/yyyy - hh:mm").format(date2));
And I am not in the same timezone as Los Angeles.
EDIT 2:
Found how to change the timezones:
// Change this:
ZonedDateTime date2 = date.of(date.toLocalDateTime(), la); // incorrect!
// To this:
ZonedDateTime date2 = date.withZoneSameInstant(la);
You can use java.time.format.DateTimeFormatter. https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html
Here there is an example
ZonedDateTime date = ZonedDateTime.now();
System.out.println(DateTimeFormatter.ofPattern("dd/MM/yyyy - hh:mm").format(date));
Many thanks for above. Here it is in scala where localDateTime.now always Zulu/UTC time.
import java.time.format.DateTimeFormatter
import java.time.LocalDateTime
import java.time.ZoneId
val ny = ZoneId.of("America/New_York")
val utc = ZoneId.of("UTC")
val dateTime = LocalDateTime.now.atZone(utc)
val nyTime = DateTimeFormatter.
ofPattern("yyyy-MMM-dd HH:mm z").
format(dateTime.withZoneSameInstant(ny))
