  Building on the recent work of C. De Lellis and L. Sz\'{e}kelyhidi, we
construct global weak solutions to the three-dimensional incompressible Euler
equations which are zero outside of a finite time interval and have velocity in
the H\"{o}lder class $C_{t,x}^{1/5 - \epsilon}$. By slightly modifying the
proof, we show that every smooth solution to incompressible Euler on $(-2, 2)
\times {\mathbb T}^3$ coincides on $(-1, 1) \times {\mathbb T}^3$ with some
H\"{o}lder continuous solution that is constant outside $(-3/2, 3/2) \times
{\mathbb T}^3$. We also propose a conjecture related to our main result that
would imply Onsager's conjecture that there exist energy dissipating solutions
to Euler whose velocity fields have H\"{o}lder exponent $1/3 - \epsilon$.
