I was thinking about potential problems in the future, when the date (the
year in particular) value increases. I have already seen such problems on
old Macs, where some applications fail to process current year values.
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.
Yes, just dealing with the year should be sufficient.
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?
1980 is the base year for the Settime() XBIOS call, so it should IMO be the
minimum for everything.
