A trivial implementation of FILETIME style timestamps .
FILETIME was apparently introduced in the Windows NT operating system and is now used in a variety of file formats and equipment, including Simrad Echosounders.
A FILETIME is an "integer value stating the number of 100 nanosecond intervals since January 1, 1601".
