Are you looking for this touch ?

man touch(1)

A method to save the last updated timestamp. Does not save the file created timestamp.

# Save the timestamp by creating an empty file with a copy of the timestamp
touch -r gr.txt gr.txt.timestamp

# Edit the file

# Restore the timestamp
touch -t gr.txt.timestamp gr.txt

# Tidy up
rm gr.txt.timestamp

You can use touch to change the timestamp to whatever you wish
