In what time format access token's parameters are returned?

[birute]

When we request a token using the user id, we receive the access token with a the following parameters; "issued_at" : "1428486235527", "expires_in" : "3599" What I would like to know is, if this time format is in UTC, GMT or BST format.

All of the Apigee internal dates are in the UTC format. The "issued_at" refers to milliseconds since the epoch, which is Jan 1, 1970 UTC.

The "expires_in" is expressed in seconds.
