The File.LastModified property gives the time that the file was last modified (or created, if unmodified) to the millisecond, so no need to convert it to minutes and seconds - just compare the values for the two files.

[By the way, if you need to compare a file modified time with the time of a file uploaded to a net location then you need to correct to UTC.]

If you want to know seconds between dates then do this.
If you want this difference in number of hours, days, etc. use the DateUtils Library instead.

B4X: 
    Dim d1 As Long = File.LastModified(File.DirApp, "page1.txt")
    Dim d2 As Long = File.LastModified(File.DirApp, "trackingRecords.txt")
    Log((d2 - d1) / 1000)        '# seconds difference, if negative d1 is later than d2
