Hi,

I am currently using the calendar\_grid library, which uses the Time  
library. My issue is that need to generate calendar grids before  
1900 but the Time library does not support any dates before then. Is  
there anything I can do to extend or shift the date range supported  
by the Time library so that I can create calendars in the 1800’s?  
Thanks in advance.

Benjamin
