 The timestamp is always given in millisecond but the time resolution can be reduced (rounded down).
 The use case is to be able to compare a build time to a file time attribute.
-On node v0.10 or with file system like HFS or FAT, `fs.stat` time attributes like `mtime` precision is one second.

-Assuming `lastRun(fn)` returns 1426000001111, `lastRun(fn, 1000)` returns 1426000001000.
