FontRedate is a Java 1.4 application to read internal dates from OpenType, PostScript, or TrueType font files, and to change the file modification dates to match. The file contents are not changed, only the date in the system file directory. Internal font dates may or may not be accurate; many fonts are created and later edited without setting the date properly. Times may differ from what you expect depending upon your time zone, and will usually agree with what the Microsoft Font Properties Extension shows in its Version tab for OTF/TTC/TTF files, plus or minus daylight saving time.
