Expiration attribute limitation - max year?

Hello I'm working on something and I can figure what is the max year for expiration attribute? Here is the problem rlm_sql: Failed to create the pair: failed to parse time string "December 31 2039 00:00:00" When I enter December 31 2035 00:00:00 as a year it works but 2039 doesn't. Is there any way to avoid this limit? I know that 2035th year is a far from now but.. :)
