Kevin,
You mention that "when I use the camonitor (from base) I get timestamps
20yrs in the future". What do you see when you type "date" on the
console of the IOC that camonitor is connecting to?

Title: timestamp question
Hi All,
I have a channel access application that we inherited from someone else a
long time ago that is
returning a timestamp of seconds since 1/1/1970. This application also has
its own camonitor
utility that returns the current date. However when I use the base
camonitor I get timestamps 20yrs
in the future.
Upon further investigation I found comments that EPICS uses 1/1/1990 as its
epoch. So I'm guessing
here that EPICS camonitor is taking the timestamp from my application and
adding 20yrs. Is this
correct or am I _way_ out in left field?
Thanks in advance.
Kevin
