Actually, as YourMother pointed out, -M is script start time minus file modification time, in days. So, you will get different results every time your script is started.

Using stat, however, will give you the actual modification time in seconds since the epoch.1 You will always get the most recent time the file was modified no matter when your script was started.

1If you don't know what the epoch is, don't worry, it's just a fixed point in time defined in a standard.
