Can Bulk Rename Utility please be enhanced to allow Auto Date (8) syntax to support values from EXIF sub-seconds fields? i.e.
SubsecTime
SubsecTimeOriginal
SubsecTimeDigitized
Refer the latest EXIF 2.32 standard which can be downloaded fromhttp://cipa.jp/std/documents/download_e.html?DC-008-Translation-2019-E . Refer pages 46 and 54-55, 127 and more... (search the PDF for "subsec"). Sub-seconds have been available in EXIF as far back as v2.2 (2002) AFAIK, or possibly earlier.
Support for sub-seconds fields would allow files, for example, to include sub-seconds such as milliseconds, in file names. This can be important to users, for example, when there was more than one photo taken per second. It allows better sorting as well, when comparing files renamed with Bulk Rename Utility and those that have been imported using other products that support sub-seconds in file names. For example,Nikon ViewNX-i software's transfer tool or Downloader Pro.
