Incompatible types: com.google.api.client.util.DateTime cannot be converted to org.joda.time.DateTime

Question

I want to convert Google DateTime into org.joda.time.DateTime.

This is the code of Google's implementation.

http://grepcode.com/file/repo1.maven.org/maven2/com.google.http-client/google-http-client/1.15.0-rc/com/google/api/client/util/DateTime.java

How I can implement this?

OK, so you don't even need `java.util.Date`, you can just use millis since epoch — Stewart, Sep 21 '16 at 14:07

getValue() as described by link given by OP:

Returns the date/time value expressed as the number of milliseconds since the Unix epoch. If the time zone is specified, this value is normalized to UTC, so to format this date/time value, the time zone shift has to be applied.

Joda DateTime constructor docs

public DateTime(long instant)

Constructs an instance set to the milliseconds from 1970-01-01T00:00:00Z using ISOChronology in the default time zone.

// getValue() return millis since epoch
long millis = googleDate.getValue();

// Which is accepted by Joda DateTime's constructor
DateTime jodaDate = new DateTime(millis);

I tested it but I get null. Probably the problem is somewhere else. — Peter Penzov, Sep 21 '16 at 14:47
`getValue()` returns a primitive `long`. It can't be `null`. — Stewart, Sep 21 '16 at 15:02

Probably it is too late, but I have just solve a quite similar problem as follows

//Let's suppose date is our google DateTime
org.joda.time.DateTime jodaDate = date.getDateTime(date.getValue);

This creates a new joda DateTime from the google DateTimes' long value
