How to use yearcutoff option in data having three centuries ?

[Aquarian27]

Hi

Suppose I have three centuries  i.e. 1800,1900 and 2000 in the data having 2-digit format date. How to read these  with the help of yearcutoff ?

Is this data all in one file/data set? If so, how do you know which century the date represents? The YEARCUTOFF option pretty much is set up only for distinguishing 19XX to 1999 from 20XX-2099 years. For 1800 you're going to have to provide the century somehow and then use an appropriate date conversion function.
