To calculate the difference in hours (with decimals) between two %TimeStamp values in ObjectScript, you can use the $ZDATETIMEH function to convert the timestamps into $HOROLOG format, and then calculate the difference using appropriate arithmetic. Here is an example approach:

Code Implementation

ClassMethod CalculateHourDifference(startTime As %TimeStamp, endTime As %TimeStamp) As %Float
{
    // Convert start and end times to $HOROLOG format
    Set startTimeH = $ZDATETIMEH(startTime, 3)
    Set endTimeH = $ZDATETIMEH(endTime, 3)

    // Calculate the difference in days and seconds
    Set dayDiff = $PIECE(endTimeH, ",", 1) - $PIECE(startTimeH, ",", 1)
    Set timeDiff = $PIECE(endTimeH, ",", 2) - $PIECE(startTimeH, ",", 2)

    // Combine the difference into hours
    Set totalHours = dayDiff * 24 + (timeDiff / 3600)

    Return totalHours
}

Explanation

1. $ZDATETIMEH(timestamp, precision) converts a %TimeStamp into $HOROLOG format with the precision value 3 for best compatibility [1][2].
2. $HOROLOG format consists of two parts: the number of days since 31 Dec 1840 and the number of seconds since midnight of the current day.
3. By calculating day and second differences separately, you can then convert the total time difference into hours.

Example

Using your provided timestamps:

Set startTime = "2024-07-12 08:30:00"
Set endTime = "2024-07-12 15:15:00"
Write ##class(YourClass).CalculateHourDifference(startTime, endTime)
// Output: 6.75

This approach ensures precision and clarity while working with timestamps in ObjectScript. [1][2]

There is no direct documentation or feature in InterSystems Package Manager (IPM) that specifically addresses handling System Default Settings for CI/CD pipelines. However, here are potential approaches based on available information:

1. System Default Settings: These settings simplify management of environment-specific configurations, such as file paths, port numbers, etc., and can be exported/imported using methods like %Export and %Import. It is advisable to integrate these methods into your pipeline processes to automate these tasks [1][2].

2. Custom Automation: While not directly tied to IPM, you can use tools or scripts, such as the GetSettingsFromProduction method, to gather and setup System Default Settings efficiently during the deployment process. This method allows filtering specific settings and automating their migration to the system defaults table [3][4].

3. Source Control: System Default Settings can be exported and tracked in version control. Each branch or CI/CD environment can include specific setting files, which can then be applied programmatically during deployment [2].

If Invoke scripts are acceptable for your case or specific automation needs, they could wrap around these export/import or automation methods to ensure smooth integration without extending IPM itself. For completely eliminating custom solutions, consider submitting a feature enhancement request on InterSystems Developer Community.

1. To list a user and their properties, including roles, you can use ObjectScript commands with the Security.Users class in the %SYS namespace. An example of listing the properties of a user is:

NEW $NAMESPACE
SET $NAMESPACE="%SYS"
SET status = ##class(Security.Users).Get("Username", .properties)
IF $$$ISOK(status) {
    ZWRITE properties
}

This retrieves the user's properties into a reference variable and displays them [1][2].

2. To add a user and set their properties, including roles, you can use the Create method of the Security.Users class. For example:

NEW $NAMESPACE
SET $NAMESPACE="%SYS"
SET properties("FullName") = "New User"
SET properties("Password") = "securepassword"
SET properties("UserRoles") = "%Developer,%Operator"
SET status = ##class(Security.Users).Create("NewUser", .properties)
IF $$$ISOK(status) {
    WRITE "User created successfully."
}

This creates a user with specified roles and other details [1][2].

3. To set a user's password, you can use the Modify method to update the relevant property, as in:

NEW $NAMESPACE
SET $NAMESPACE="%SYS"
SET status = ##class(Security.Users).Get("Username", .properties)
IF $$$ISOK(status) {
    SET properties("Password") = "newpassword"
    SET status = ##class(Security.Users).Modify("Username", .properties)
    IF $$$ISOK(status) {
        WRITE "Password updated successfully."
    }
}

This updates the user's password [1][2].
