Abstract
The proper-time resolution function for the measurement of the time evolution of B
mesons with the Belle detector at KEKB is studied in detail. The obtained resolution
function is applied to the measurement of B meson lifetimes, the B0B0 oscillation
frequency and time-dependent CP asymmetries.
