Matt Newville is maintaining it. I think he is at ESRF right now.

I’ve found the problem — the code in lib/dbr.py looks just plain wrong:
EPICS2UNIX_EPOCH = 631173600.0 - time.timezone
. . .
def make_unixtime(stamp):
"UNIX timestamp (seconds) from Epics TimeStamp structure"
return (EPICS2UNIX_EPOCH + stamp.secs + 1.e-6*int(1.e-3*stamp.nsec))
Problem one — that constant is wrong. The correct value, as defined in <base>/include/epicsTime.h is: #define POSIX_TIME_AT_EPICS_EPOCH 631152000u
Problem two — what’s ‘time.timezone’ doing in there? The unix time stamp is in UTC as is the EPICS time stamp.
I propose the following fix:
diff -u lib/dbr.py.orig lib/dbr.py
--- lib/dbr.py.orig 2014-05-12 16:37:58.000000000 -0700
+++ lib/dbr.py 2014-05-12 16:38:00.000000000 -0700

Who’s maintaining the pyEpics stuff now?
