Internal function valid-timestamp-p could be smarter about restricting the valid integer range for YEAR arg.

local-time::valid-timestamp-p 000001 0 0 0 28 2 most-positive-fixnum)
;=> T

(local-time::valid-timestamp-p 000001 0 0 0 29 2 most-positive-fixnum)
;=> NIL

(local-time:encode-timestamp 000001 0 0 0 29 2 most-positive-fixnum)
;=> error

(local-time:encode-timestamp 000001 0 0 0 28 2 most-positive-fixnum)
;=> error

I've posted some some suggestions for the above and for tweaking local-time in general at following gist:
