I find it odd that two digit years are translated to 19nn, especially since we’re over 20 years into the 21st century or, conversely we could be dealing with older historical data. Documentation states: “If the date to be converted has only two year digits, it is treated as a date between 1900 and 1999. E.g. “31/1/19” is interpreted in d-M-yy format as 31st January 1919.”
It’d be nice if the century was customizable.
