# Write out the tags. Extract the YYYYMMDDHHMMSSmmm date from the filename and

# 'YYYY:MM:DD HH:MM:SS' format expected by exiftool, the tools seems smart
# enough to handle anything that looks close to a legitimate date/time.

# Although the milliseconds are parsed, I'm not sure that level of
# granularity is captured in the tags.
