title: Is there any built-in way to list all the save time of the last edited files?
body: <p>My work as a web programmer involves a lot of editing files from remote servers using vim. I need to report how much time it took to solve a particular case, and I have a little trouble with it: I can't get used to time tracking software, because I always forget about the fact I need to track my time. This is only an issue in cases that take a little amount of time, from about 5 to 60 minutes. </p>
  
  <p>However, as far as I do all my work in vim, I'm wondering if there is any way to see which document was saved at which time. Of course, I can define some autocommands which save current time and filename to a certain file, but is there a built-in feature to do so?</p>
