6 bit is a typo in my above post, should have been 64 bit as opposed to 32 bit in the past.

Do you have a problem with cookies that expire too early?

No, but I need to know what maximum epiration date can be set to the browser by server- 15, 20, 25 years?

Be safe and do not go beyond 2038 (there is bug 562198 on Linux that has just been fixed). There is no need to go further than a few years. Firefox should be able to store an expiration date to at least 3000 using a 6 bit date, but there is no need to go that far.

Ok, thank you for help. But what do you mean under 6 bit date value? What the maximum (after bug fix f.g.)? Is it 100, 200 years or more?

Or can the maximum be different for the different browser's versions?
