we want

1000e^.06x = 1100(1+.06/365)^(365x)

x = 202,800 years

as for solving the equation, there's no useful symbolic method. Some kind of numeric approximation will probably be needed.

The time seems rather large. Probably because daily compounding is very nearly continuous, and 1100 gets a pretty big head start over 1000.

You sure the interest rates are the same?
