# Testing replication delay reporting (bug#29309)
# there is an unavoidable non-determinism in the test
# please compare the results with the comments

### bug emulation

connection master;
drop table if exists t1;
create table t1 (f1 int);
sleep 3;

#connection slave;

flush logs /* contaminate rli->last_master_timestamp */;

connection slave;
--echo # bug emulated: reports slave threads starting time about 3*3 not 3 secs

### bugfix
