Fix output formatting
Added check-timestamp.pl

The script reports warning or critical when a
monitored file is older (or newer) then the specified
treshold.

  --file=FILE     File to check

  --warn-age=SEC  Warning if FILE is older than SEC.
                  If SEC is negative alert if FILE
                  is newer then -SEC. Default: 90000

  --crit-age=SEC  Critical if FILE is older than SEC.
                  If SEC is negative alert if FILE
                  is newer then -SEC. Default: 180000

  --mtime         Check FILE's "mtime" timestamp.
                  That's when the file's content was
                  last modified. This is the default.

  --ctime         Check FILE's "ctime" timestamp.
                  That's when the file's metadata were
                  last modified.
