I had dozens of scripts using java datetime libraries and datatypes and nearly all of them will literally write the wrong time to tags or insert queries. If I print it to the console or convert it to a string, it writes the correct time. If I write it to a tag or database, it usually writes the correct time subtract 4-5 hours. Makes no sense and seems like a pretty massive bug in 8.0.
There are a lot of potential variables in what you’re describing - can you get in contact with support so we can have someone take a closer look at what you’re doing and what might be going wrong?
In short: to answer the question in the title, no, they are not to our knowledge - that doesn’t mean they couldn’t be, but this is the first report of this issue I’ve seen.
I upgraded from 7.9.10 on a new server with a restore of my gateway backup. I ran the new server in production to see if all was well. I upgraded to all the versions systematically to get to version 8.0.6. Now, running my new server, I get script faults saying my datetime conversions are leaving the decimal in the seconds and fail out. There has to be some changes.
no to mention, I can’t get my barcode scanners to work either…still working that issue as well

here is the script that works fine in 7.9.10
for row in rs:
dt = row[“Date”]
Wed Nov 01 00:00:00 CDT 2017
date_format = "%a %b %d %H:%M:%S %Z %Y" dta = datetime.datetime.strptime(str(dt), date_format) dbdatetime = datetime.datetime.strptime(str(dta), '%Y-%m-%d') dbdatetimestr = str(dbdatetime) dbdatetimestr = dbdatetimestr[:10]
Does this by chance happen to correspond to UTC time?
Uhm, those aren’t java datetime types, but Jython. Jython changed from v2.5 to v2.7. I’ve always found python date/time objects to be less than reliable in jython, even before v8.
Are you just extracting the date? Two options for you:
- dbdatetime should use strftime instead of strptime
dbdatetime = datetime.datetime.strftime(dta, '%Y-%m-%d')
- Ignition has all sorts of new date functions for us to use.
for row in rs: dt = row[“Date”] dbdatetimestr = system.date.format(dt, 'yyyy-MM-dd')
