⏰ 时机 = time + machine; the right moment when the clock clicks into place
时 means time or hour; 机 means machine or opportunity. Together they name the precise occasion when conditions align — the mechanical click of timing. Same 机 appears in 飞机 (airplane) and 机会 (chance).
时 — sun 日 + temple/measure 寺
Originally a phono-semantic compound: 日 (sun) gives the meaning of time or season, while 寺 (shí) supplies the sound. Early forms used 之 as the phonetic before 寺 replaced it. The core sense 'season, time, hour' has stayed stable since ancient Chinese.
