Hi there,
I found this helpful api Last updated to get items update since a particular time.
The documentation does not mention the exact format of the date/time to be passed as input. Would appreciate any help on this.
Thank you 
Hello there @kranthi_thoughtflow,
You can not update that column yourself via API. You can only read it.
Let me know if you have any other questions 
Cheers,
Matias
