How can I get the expire time for the particular item in memcached

Question

In runtime, I want to retrieve the expire time info about some items in memcached. I didn't find any related interface on memcached. Can I do this? something like: mc.get_expire_time('key')

Thank you

According to memcache protocol (both text and binary) niether get nor gets return expiration time. And there is no other method to retrieve it. But sure you can pack expiration time into value along with what you store now when you set/add it to make it retrievable.
