Hi Andy and thank for reply,
The memcached expiration time is clear, everything which exceeds 30 days (in
seconds 60*60*24*30 = 2592000) it is treated like an Unix time stamp.
According to the memcached log I've got something like 'set
app_cake_model_default_aros_acos 1 86313600 699'
The magic number 86313600 I *think* it's the expiration value, 86313600 is
greater than 2592000 so it's treated like an Unix timestamp, date('Y-m-d
H:i:s', 86313600) = 1972-09-26 02:00:00 pretty much the same as
date('Y-m-d H:i:s', strtotime("+999 days") - time()) (part of the line from
source code I brought into discussion)
You have perfectly right, until I don't demonstrate this with an unit test,
the code is considered correct.
I see there is already a
test, cake/tests/cases/libs/cache/memcache.test.php, I'll run it and I'll
get back to you.
Thank you for your help,
Adrian
