Customizing the Duration Display Format
Duration is displayed in two locations in the ThingWorx Apps:
• Asset Advisor—
• Alert Monitoring—
Duration is displayed in the following format:
• For times greater than 1 day, in days and hours: 6 days 3 hrs
• For times greater than 1 hour, in hours and minutes: 3 hrs 27 mins
• For times greater than 1 minute, in minutes and seconds: 1 min 42 secs
• For times greater than or less than 1 second, in seconds and milliseconds: 6 secs 78 ms, or 0 secs 12 ms
 | Milliseconds only display when the includeMS input on the service implementation is set to true. By default, includeMS is set to false. |
To customize the format for displaying duration:
1. In ThingWorx Composer, open the PTC.SCA.SCO.TimeFormatHelper Thing.

to override and edit the service.3. Enter custom Javascript code for your desired duration format. For example:
◦ To display the duration in seconds only, in the format "## seconds":
result = duration/1000 + " seconds";
◦ To display the duration in seconds and milliseconds using the includeMS input, in the format "## seconds ## milliseconds":
var numOfSeconds = Math.floor(duration / 1000);
var numOfMilliseconds = duration % 1000;
if (includeMS = true) {
// Show seconds AND milliseconds
result = numOfSeconds + " seconds " + numOfMilliseconds + " milliseconds";
}
if (includeMS = false) {
// Show only seconds
result = numOfSeconds + " seconds";
}
var numOfMilliseconds = duration % 1000;
if (includeMS = true) {
// Show seconds AND milliseconds
result = numOfSeconds + " seconds " + numOfMilliseconds + " milliseconds";
}
if (includeMS = false) {
// Show only seconds
result = numOfSeconds + " seconds";
}
4. Click Save and Continue, then click Done to save the updates to the service.
5. Click Save to save the Thing.
