How can "set timestamp" be a slow query?

replication

My slow query log is full of entries like the following

# Query_time: 1.016361 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 SET timestamp=1273826821; COMMIT;

I guess the set timestamp command is issued by replication but I don't understand how set timestamp can take over a second. Any ideas?
