On older versions, when I saved a script it kept the most recent time and date. This allowed me to easily use Windows Explorer to move the most recently changed scripts to a backup disc each evening.

With version 15B I notice that if I change an existing script and save it, the script keeps its original time and date so when I look at the directory of scripts the most recently changed scripts are hard to find. Is there a way to modify the editor so that the current date and time are attached to the file when it is saved? Thanks.

Once the script is modified it should show the most recent time it was modified.

Is this behavior reproducible? Also, are other file types also showing the same behavior? I was not able to reproduce this behavior on Windows 7 64-bit and MAC OSX Yosemite.

If you experience this issue consistently, you can create a Technical Support Request .

Changes in modification time happen at the operating system level, and are part of the POSIX definition of the file I/O calls. A program would have to specifically change the times back (using utimes() or utime()) in order for there to be no change in the times.

It would be more likely that the file you are looking at was not the one being changed (or that the file you are looking at is a symbolic link to the file being changed)
