Comment 4 for bug 886059

It appears... That my pt-heartbeat running in EST and PST were in fact not working at all (i.e. regardless whether slave was working it reported 0secs).... but I managed to get them to work with:

EST pt-heartbeat -D <database> -u<user> -p<pass>--monitor -h --skew -18000
PST pt-heartbeat -D <database> -u<user> -p<pass>--monitor -h --skew -28800

By that rationale in IST I could add "--skew 19800" and wait 5.5hrs for output and it would be at 0secs

p.s. Really enjoyed the Percona Live talks in London.
