Hello,
You might have to leave the type as an octetstring and parse the hex value on a QAction to return a double value and then set that double value to another parameter of interprete type double with measurement type date number.

So for example: (a quick method made in copilot)
private static double ParseDateValue(SLProtocol protocol, string value)
{
if (string.IsNullOrWhiteSpace(value))
throw new ArgumentException("Invalid input");

value = value.Replace(".", "");

// Required: YYYYMMDD (hex)
if (value.Length < 8)
throw new FormatException("Invalid date format");

int year = Convert.ToInt32(value.Substring(0, 4), 16);
int month = Convert.ToInt32(value.Substring(4, 2), 16);
int day = Convert.ToInt32(value.Substring(6, 2), 16);

int hour = 0, min = 0, sec = 0, ms = 0;

if (value.Length >= 12)
{
hour = Convert.ToInt32(value.Substring(8, 2), 16);
min = Convert.ToInt32(value.Substring(10, 2), 16);
}

if (value.Length >= 16)
{
sec = Convert.ToInt32(value.Substring(12, 2), 16);
ms = Convert.ToInt32(value.Substring(14, 2), 16);
}

// Ignore timezone (same as original)
var dt = new DateTime(year, month, day, hour, min, sec, ms);

return dt.ToOADate();
}

And you want to set the return value to a parameter like this:

<Param id="1" trending="false">
		<Name>ParsedDatetime</Name>
		<Description>Parsed DateTime</Description>
		<Information>
			<Subtext></Subtext>
		</Information>
		<Type>read</Type>
		<Interprete>
			<RawType>numeric text</RawType>
			<LengthType>next param</LengthType>
			<Type>double</Type>
			<Decimals>8</Decimals>
		</Interprete>
		<Display>
			<RTDisplay>true</RTDisplay>
		</Display>
		<Measurement>
			<Type options="date">number</Type>
		</Measurement>
</Param>

Hi Alex,

Can you try the suggestions described in these questions:

• Driver: convert hexadecimal value to letters
• Converting SNMP octetstrings to readable ASCII in xml code

Hope it helps.

Update:

Having a look at the OID definition:

It seems that changing the type will not make a difference. Looking at other connectors that implement the same OID, I noticed that a QAction is required to parse the raw data so the datetime can be displayed correctly in the parameter.
