Can you explain "I want my colleges to be able to insert their own timestamp, not "set" the current time."
Do you want them to Manually type the time?
Because with what i did, when the click they the button, it will capture the time into the textbox. If you want them to manually enter the time, then you only need the Patch.
Patch(YourTable,Defaults(YourTable),{TimeColumn:TextBox1.Text})
And the "TimeColumn" do I have to make a new column in the sharepoint list with just a textfield?
The column name TimeColumn is just a sample i gave. Replace TimeColumn with where you want to save it to in your Table
Also ensure you use the actual name of your table. Also change TextBox1.Text to the name of the actual textbox on the screen
