I have a cluster with three mongod instances,three config servers,and one mongos.ALL of them have the same time.
Something appears in the mongos log like this:

Wed Jul 31 12:22:15.762 [conn2] autosplitted test1.test1 shard: ns:test1.test1shard: sh3:sh3/192.168.69.46:10003,192.168.69.54:10003,192.168.69.55:10003lastmod: 1|4||000000000000000000000000min:

(splitThreshold 47185920) (migrate suggested, but no migrations allowed)
