Issue with Azure Logic APP EPOCH DATE Conversion - azure

Question

I have an issue with epoch date conversion in Azure logic app.
I cannot figure out what I'm doing wrong here.
I have divided my logic app in different steps to first get the Timestamp and remove "/Date" and the trailing "/".
And then I use the add to time function where i am getting an unexpected result.
Input:
"EndDate": "/Date(253402214400000)/",
"StartDate": "/Date(946684800000)/"
Expected output
"EndDate" : "2000-01-01T00:00:00",
"StartDate": "9999-12-31T00:00:00"
Current result:
"EndDate": "1942-11-15T20:26:40.0000000Z",
"StartDate": "2026-10-14T16:21:20.0000000Z"

After reproducing from my end, we have observed that you have used the value in milliseconds. Try converting it into seconds and follow the same approach. Below is the code I'm using -
{
"root": {
"CostAccountID": "#{body('Parse_JSON')?['root']?['CostAccountID']}",
"EndDate": "#{addSeconds('1970-01-01T00:00:00Z', div(int(body('Parse_JSON_2')?['root']?['EndDate1']),1000))}",
"StartDate": "#{addSeconds('1970-01-01T00:00:00Z', div(int(body('Parse_JSON_2')?['root']?['StartDate1']),1000))}"
}
}

I have made changes to your code view. Below is the updated one
