Though [[Special:Ipblocklist]] shows the expiry time, no blocks appear to be expiring when they're meant to. In fact, this morning I had to unblock a bunch of IPs and users whose blocks expired yesterday or the day before.
Possibly related to bug 856, bug 1156
Should be fixed now; it was comparing timestamps in the wrong format.
