twelve o’clock

One of a full set of twelve analog clock-face emoji (each hour on the hour), technically meant to represent literal times but almost always used loosely as 'clock face, time passing' filler rather than precisely meaning noon or midnight. Trivia: this whole 24-emoji clock-face family (12 on-the-hour plus 12 half-hour) was included from the very first 2010 Unicode set, an oddly complete detail for such an early release.
