Which is the database table in which Boost stores the cache expiry time of a node and what is the column name? I was looking for a way to manually set the Boost expiry time of a node and happened to chance upon the boost_cache table. There is an expire column and I am assuming that it contains the timestamp denoting the expiry time of the database. Then I happened to see the timer column and now I am confused as to which column houses the expire timestamp.  Could someone explain?

Site runs on Drupal 6.
Basing on boost_schema(), the description of those fields is the following:


expire: UNIX timestamp for the expiration date of cached page
timer: Time in milliseconds that the page took to be generated


The expiration time is contained in the "expire" database column.
