I think best option to work around that would be to add "RTC year" 
option (e.g. "--rtc-year 1990").  Hatari would then internally offset 
year from gettimeofday() with suitable amount.

(Offset instead of a fixed year is needed internally so that running 
emulator over new year works OK.)

What would be suitable minimum year accepted by such option, should it 
be TOS version, or machine type specific, or would e.g. 1985 work as 
minimum for everything?
