[HECnet] The new few centuries (or DATE75)

Oh you mean the 'orange' book?? Yeah, they were great. Your observation that not all months have 31 days is, of course, correct.? I think what it's telling me is that DATE75 is /not/ the monitor internal format, but rather a method of encoding and conveying the current date.? Explicit, the monitor is never going to have the DATE UUO give February 30^th and 31^st and maybe not the 29^th .? It would be worth a look if you know what module it's in (I don't have Tops-10 sources). Internally, Tops-10 is likely maintaining two clocks, a JIFFY based uptime counter and a time of day based on 18 bits of a day count from 1858 and eighteen bits of a fixed fraction of day/(2^^18 ), which yields a resolution of about ? of a second. Tops-10 is almost the same except that it uses milliseconds as an uptime counter.
