I don't think there is such a record readily available.
However it should be relatively straight forward to develop something that
could generate the data you're looking for.
The program would:
* Browse trough the git history of mediawiki-config.git (optionally picking one
per day, or every commit if you like)
* Use a PHP interpreter to run CommonSettings.php with site context
dbname=enwiki. No need to explicitly have it read InitialiseSettings.php since
that is referenced from CommonSettings.php
* Fetch list of run-time included php files
* Filter for $IP/extensions/*/*.php
* Strip to match only directory name
* Insert into database of some sorts with timestamp of commit
From there you'll be able to determine exactly when and for how long an
extension was deployed.

PS: The public mediawiki-config.git only dates back to 24 Feb 2012. Before that
date the information was in a non-public svn repository inside the
wmf-production cluster.
