Subject: Archive Dump on Change Only

Greetings EPICS Experts,

I am trying to dump archive data for some setpoints but am only interested in values 
when they change.  Is there an easy way to only print out values only once they change?  
I was trying something like the following:

arget -s '2016-8-1 00:00:00' -e '2017-8-1 00:00:00' -c 1000 PVNAME

but this gives:
...
2016-10-19 16:58:58.343624 220.0
2016-10-19 16:58:59.367182 220.0
2016-10-19 16:58:59.877238 220.0
2016-10-19 16:59:00.399215 220.0
...

Thanks for your help,

-Dean Hidas
