r1: one time-format util — src/Format.vala's format_stamp owns the '%Y-%m-%d %H:%M' display shape; the four per-entrypoint format_stamp/format_time copies and the saddles/rules/projects inline formats collapse onto it (StatePulse keeps its second-precision pulse stamp); the clock domain is uniform now_local (PushService's VAPID exp was the lone now_utc, and to_unix is timezone-independent anyway).
