Time-sensitive content may be assigned a token that expires after a specified time period. Requests that are submitted after the expiration date will be denied.
The Expire parameter (i.e., ec_expire) defines an expiration date and time by the number of seconds that have elapsed since Unix time (a.k.a. POSIX time or Unix epoch). Unix time starts on 1970-01-01 at 00:00:00 GMT.
Language-specific functions that provide Unix time conversions are widely available. However, at times it may be necessary to manually set this parameter or to troubleshoot an existing token. There are a variety of websites that provide conversion to and from standard time conventions to Unix time.
Set the Expire parameter to the following value to expire the token at 12/31/2015 12:00:00 GMT:
A request submitted after 12/31/2015 12:00:00 GMT will be denied if it leverages a token generated using the above parameter.
