Someone in an hydrological bureau had the same shock today reading that
LRM topic in AdaHelp, but because of the 1901 problem: many archived time
series begin before 1901... (hydrology, geography etc.) => Calendar is
useless for it ! One has to program a Calendar bis. It's not that
the formulas for this purpose don't exist or are too complicated...
And what to think about astronomical calculations / previsions ?...
