Unforeseen results occur when calculating time difference in seconds in PHP by converting two dates to Unix timestamps.

According to the title, I'm trying to find the difference in seconds and then convert those seconds to days and hours. After reading and following similar questions, I built a function that adds the hour, day, week, month, or year I want to today's datetime, and I get the correct results from this part. However, I then try to convert the two dates (start date and move date) to unix timestamps, subtract both timestamps to find the difference between the two dates in seconds, and then convert to days or minutes (/86400 and /3600) I don't get the results I expected. This is the code..&

Ag-Grid: Is it possible to style a row on a timer, rather than based on the data in the row?

I need to change the background color of rows after some time. There is a column in the grid with time in seconds and I need to change the row color after 50% of that time has passed. The data in the grid itself doesn't change, so using rowClassRules doesn't seem to work as nothing changes to trigger the data to be evaluated against the rules. Instead, I thought of using the setTimeout() function with a delay, but couldn't figure out what would be done inside the setTimeout block to apply the css class to the rowNode. I don't want to change any data in the row itself. worst
