Answer 1

java.time

The Joda-Time team has told us to migrate to the java.time framework built into Java 8 and later. The java.time framework is defined by JSR 310. Much of the java.time functionality has been back-ported to Java 6 & 7 and further adapted for Android.

Offset

The java.time classes include OffsetDateTime to represent a moment on the timeline with an offset-from-UTC but not a full time zone.

The java.time classes use the standard ISO 8601 formats by default when parsing or generating strings. So no need to define a formatting pattern.

String input = "2012-01-19T19:00-05:00";
OffsetDateTime odt = OffsetDateTime.parse( input );

Time Zone

A time zone is an offset plus rules for handling anomalies such as Daylight Saving Time (DST). A proper time zone name uses a continent/region format. You can assign a time zone (ZoneId) to an OffsetDateTime to get a ZonedDateTime.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = odt.atZoneSameInstant( zoneId );
