{{#time}}, being based on the PHP function strtotime(), does not work with dates before 1970-01-01 (or dates before 1901-12-13, depending on the PHP version). In the absence of string manipulation functions, #time is the only way to make templates which are intuitive to use and still look nice. (For example, some citation templates need the date both in text format for display, and in number format for metadata.) Please extend it to dates before the Unix epoch.
