구현 주석

Pure bucket selection against an explicit clock. Returns null for null/undefined/invalid input. Thresholds: <60s just-now, <60m minutes, <24h hours, <30d days, <12mo months, then years.

Calendar-unaware by construction: a month is exactly 30 days and a year is exactly 12 such months — 360 days, not 365. This reproduces both source apps bit for bit; the drift is a systematic early promotion of about five days per year, so days = 360 already renders as one year.
