Note that FILETIME is a UTC time - so we must all make sure we use
GetSystemTime instead of GetLocalTime (or equivalents) when
obtaining the current time to compare with or write into the file.

UTC time will be safer than an explicit time/date in local time,
since it avoids problems when the clocks go forward in spring (when
the hub would suddenly think it hadn't heard from any of the clients
for an hour).

How will this 64-bit number be written out?  Decimal number or 16
digit hex value?

BTW, can fprintf etc handle 64-bit integers?
