c# - is it possible not to expire for CacheItemPolicy.AbsoluteExpiration at the specific time? -

is possible not expire cacheitempolicy.absoluteexpiration @ specific time?

msdn there written:

the period of time must pass before cache entry evicted.

as understand sentence means no less than specific time... possible if set 12 hours, record expire (let's say) in 12.5 hours? (i mean it's not documented, take not less 12 hours, 12.5 hours possible or more, right?)

for example: set updatecallback , absoluteexpiration = 60seconds cacheitempoice, in practice it's called once in 80 seconds. (i logged it)

inside updatecallback set new values cacheentryupdatearguments, mean new updatedcacheitem (the same key , new data) , updatedcacheitempolicy (the same period of time , same updatecallback)
