How do I add current timestamp into the serving code?
When creating and setting up a new ad, you can put an always-changing value into the ad code for cache busting or as a random number. The macros[timestamp], [cachebuster] (or [cache_buster]) will be replaced with a time stamp by our ad server for each ad serving. The time stamp is the number of seconds since January 1, 1970. The macros [randomnumber] (or [random_number]) will be replaced with a random number.
Example
When creating a new image ad, these are the URLs:- Image URL
https://www.example.com/ad.gif?[timestamp]
- Click URL
https://www.example.com/landing.page?[timestamp]
- Image URL
https://www.example.com/ad.gif?1734785240
- Click URL
https://www.example.com/landing.page?1734785240
This placeholder or macro is used by many different ad serving systems, including DoubleClick's DART ad server, to avoid ads being cached by the client's browser. Different ad servers can use different naming conventions for this parameter. On the other hand, if you must retain the original macro [timestamp] and do not want it to be replaced, use [asis_timestamp].
