MatSerSet does not work in year is less than 1583

MatSerSet does not work in year is less than 1583.

The funny question is why that year 1583.
We want to know, we want to believe...

Was 1583 the begin of the time?

---

Set data = For(1,100 , Real( Real x){ Floor(Rand(1,7))});

Set out1 = MatSerSet( SetRow(data), Anual ,y0001); Don´t Work
Set out2 = MatSerSet( SetRow(data), Anual ,y1582); Don´t Work
Set out3 = MatSerSet( SetRow(data), Anual ,y1583); OK
Set out4 = MatSerSet( SetRow(data), Anual ,y9999); OK

Sorry but no thing related to dates will work before 1582-10-15: the first day of the gregorian calendar that is the only standard calendar used around the world, with local ones where exist.

Dates before 1582-10-15 doesn't exist properly in this calendar because there are no universal standard before this date.

This problem could be solved using an extrapolation of the gregorian calendar or something like this but it's expensive and useless in order to solve real problems.

Certainly, this explanation should be available in TOL documentation and it will be thus in future.

Thanks to report it
