I have left my Delphi IDE open on my work computer overnight with a project open. Just now, I connected to my work computer via Windows Remote Desktop, and was prompted...
Module [file path.pas]'s time/date changed. Reload?
The same message appeared for each and every file in the project which was open.
Should I be worried about this? Did anything really change? I checked the source and nothing is different.
It just so happens that Daylight Savings Time has just ended, where all areas which observe it have just gone back an hour in time. The Delphi IDE does not know this, and therefore the date/time of all the files open will be an hour different from reality.
I expect that a lot of people will be seeing this today or tomorrow, or whenever they get back to their IDE which was left open during the time change.
