Syntax
Argument
Description
time1
(Required) - shows the starting date and time from which we need to calculate elapsed time.
You can input the TIMEAGO function from the above code directly into a cell, or you can use the setFormula method to apply the formula.
Usage notes
The TIMEAGO function is meant to make it easier to calculate the time passed from a starting point to a current point in time
It's usage is mostly common on project management.
You can use the TIMEAGO function if you want to show something more relative to a specific time rather than a straightforward date.
Benefits
This function allows you to have a calculation of the interval passed between 2 moments without having to create complicated custom functions and methods.
