I'm currently implementing a small open source backup tool (dub), and

Having unfortunately not understood how to do this from the SysTime
documentation, in despair, I've tried to directly serialize the 16 bytes
of the SysTime value. This worked fine until I call the ".toISOString()"
on the deserialized SysTime, which inevitably crashes the executable ;)
That is probably a bug. I serialize SysTime as long by means msgpack for
exchanging between C++ client and D server and it works pretty nice.
Anyway, that's not really want I intended to do, as in practice a
"ulong" already has enough resolution for that purpose.
So sorry for my ignorance, but I would definitely need some help on how
to :
- convert a file modification SysTime to a serializable number, for
instance the number of hectonanoseconds since 1/1/1970 in UTC;
- convert that number back into a SysTime that I can compare to the
modification SysTime of the same file.
