Phase is so important in miking instruments, and being also a function of time, hence distance (sound speed is painfully slow), makes so much important to place microphones not just in the right place to obtain the wanted sound, but also at the right distance to the instrument to avoid phasing issues. Any drum miking text will tell how to place for example overheads equally distanced to the snare drum to avoid issues. Even the famous Glyn Johns technique, which uses only 3 mics at different heights, recommends to make sure they're kept at the same distance to the snare drum.
