Hello!
I need some help, I have an issue where the minutes output is decreasing instead of increasing, my task is to display inside the dashboard the total runtime of the machine from 7 AM to 7PM but the total time for example will start at 300 minutes decreasing to 299 min and so on.

It would help if you could post result of your MSSQL Query output for two pulse. (the contents of debug2 in your example)

@smanjunath211
the data is more that 999 so this is the latest output

There’s a great page in the docs ([Working with messages : Node-RED](https://nodered.org/docs/user-guide/messages)) that will explain how to use the debug panel to find the right path/value for any data item.
Pay particular attention to the part about the buttons that appear under your mouse pointer when you over hover a debug message property in the sidebar.

Would you like to share what the 'solution' was, so other people can benefit from your experience? You could also mark your thread as solved.

Instead of adding the total time, I changed my approach with a timer that start at 7am and stop at 7pm. The timer will only count the true state and pause at false state.
