It's capable of throwing an error (see
timestamp2timestamptz_opt_overflow).  Now, maybe that's unreachable, or
maybe we could rerrange things to remove it.  But there's still enough
code underneath the timezone conversion requirement that I'd be very
hesitant to apply a leakproof marking.  In short: it might be leakproof
in practice, but we don't wish to offer a guarantee.
