lease starts < ends

[Sue True]

I've seen entries like this on both primary and failover servers lease 
file for an expired lease, which lease starts time less than 
ends time, here is the log entry:

Jun 10 11:30:56 dhcp-1 dhcpd: DHCPACK on 10.79.76.225 ends 2014/06/10:16:00:56 to 00:1a:a0:c7:b9:03 (BQ903F1) via 10.79.75.252

Note the 'ends 2014/06/10:16:00:56' part is a local hack for log 
processor.

Anyone seen this or know why?

lease 10.79.76.225 {
   starts 3 2014/06/11 11:54:32;
   ends 2 2014/06/10 16:00:56;
   tstp 3 2014/06/11 11:54:32;
   tsfp 3 2014/06/11 11:54:32;
   atsfp 3 2014/06/11 11:54:32;

   hardware ethernet 00:1a:a0:c7:b9:03;
   uid "\001\000\032\240\307\271\003";
   set vendor-class1 = "MSFT 5.0";
}


Thanks!
