How to Obtain the Current Date and Time in UTC or GMT with Java
When initially creating a Date object, it's initialized to the current local time zone. To retrieve the current date and time in GMT or UTC, use the following methods:
Using Java 8's java.time package
Instant.now(); // Capture the current moment in UTC.
Instant.now().toString();
Result:
2016-09-13T23:30:52.123Z
Using Joda-Time
new org.joda.time.DateTime(org.joda.time.DateTimeZone.UTC);
new org.joda.time.DateTime().toDateTime(org.joda.time.DateTimeZone.UTC);
Result:
2014-01-21T23:34:29.933Z
Recommended Practice
Specifying the desired time zone is recommended, as relying on the default time zone can lead to confusion and bugs. Use the appropriate DateTimeZone to set the intended time zone.
For UTC:
DateTimeZone.UTC
For the JVM's Current Default Time Zone:
DateTimeZone.getDefault()
