Ciao Mohammad I think this is a fascinating topic where computer science meets social behaviour. A little while ago there was a related interesting thread ... https://groups.google.com/d/msg/tiddlywiki/YaFzHXfjnFc/Rhkybx0BAQAJ
That thread was concerned with date RANGES in TW standard date mechanism (it only works from 1899 11 30 00:00:00.00 on in Gregorian). Regarding your OP, its worth mentioning that accurate historical dating that goes back a long, long way is more needed by astronomers than historians or social scientists. The modern concept of date recording becomes less workable the further you go back in time. In pre-industrial revolution societies every century back "universal" dates become rarer. Mainly used on official documents. Otherwise date recording conforms more to local perception of agricultural peasants--I.e. based on empirical observation of crop cycles. The meaning here is: better dating in TW would be good but only necessary back far enough with accuracy for practical aims. Just comments.
