Do not let the title of this article confuse you; we are not planning to take the InterSystems staff out to a fine Italian restaurant. Instead, this article will cover the principles of working with date and time data types in IRIS. When we use these data types, we should be aware of three different conversion issues:

1. Converting between internal and ODBC formats.
2. Converting between local time, UTC, and Posix time.
3. Converting to and from various date display formats.

Hi everyone,

I’ve set up a scheduled task in InterSystems IRIS to run every night at 2:00 AM, but it doesn’t seem to trigger consistently. Some nights it works as expected, but other times it just skips without any error in the logs.

The task is marked as enabled, and there are no conflicts in the Task Manager. I’ve double-checked the system time and time zone settings all looks fine.

Hello

I want to get the property of a class, sorted by order in storage.

I am making a FHIR request against Epic, in when I get the Response back using "fromDao" I am extracting the stream into HS.FHIRModel.R4.Patient. However, the patient's name comes back as name within a list that references HS.FHIRModel.R4.SeqOfHumanName.

• How do I extract the name from HS.FHIRModel.R4.SeqOfHumanName?
• Do I have to then do another "fromDao" to pull the list into string format?
• How do I navigate around the lists that are in a FHIRModel response, to extract the string values?

1. I like the Application Error Log functionality a lot. However, it becomes time consuming to inspect it date by date and directory by directory on a multidirectory server. Ideally, I would use an existing error class to write a custom error report by date, selected namespaces, etc. Does such a system class actually exist? Not that I found. The detail level on the screenshot below is enough.

Hi Community

I'm working on a complex piece of rules that needs to check each OBX and evaluate if 3 of the fields match certain criteria. I've tried to achieve this using a Foreach loop, which does work, however it is not as clean as I wanted it. I was hoping I could assign temp variables inside the foreach loop to make the rules more easier to read, for example @testCode @resultText. This is not support as you can only assign inside a when condition. Before I raise this as an idea, i wondered if there was an alternative way to achieve the same thing?

Hi,

sometimes we need more then one Iris container at the same time. Since as containers they always have the same instance name shown in the management portal, it is hard to distinguish the management-portals of the instances. Searching for a way to make it easier I thought I could change the instance name shown in the management portal. I tried "iris rename" in different ways but could only change the configuration name which is shown by "iris list", not the name in the management portal.
