The SQL query to expire old tokens truncates the date

When Crowd issues a SQL query to expire old tokens (older than a certain reference timestamp), it is truncating the timestamp to a date, i.e., it ignores hours, minutes, seconds.

This is the query as seen in the PostgreSQL logs:

delete from cwd_token where last_accessed_date<$1

with parameter $1='2013-01-08 00:00:00'

Consequently, tokens that should be expired are not being expired if the default session duration is in the range of hours or less.
