Common Instance Methods

Method	Example	Purpose
format()	m.format('YYYY‑MM‑DD')	String formatting
add() / subtract()	m.add(1, 'day')	Date math
diff()	m.diff(other, 'hours')	Time difference
startOf() / endOf()	m.startOf('day')	Snap to unit
isBefore / isAfter	m.isBefore(other)	Comparison
unix() / valueOf()	m.unix()	Timestamp (seconds / ms)
clone()	m.clone()	Immutable copy

Quick example

onTick = (length, _moment, _, ta, inputs) => {
  // current day of month (1‑31)
  const today = _moment().date();

  // parse a UTC timestamp
  const asUtc = _moment.utc(1632596400000).format('YYYY‑MM‑DD HH:mm');

  // 3‑hour duration
  const dur = _moment.duration(3, 'hours').asMinutes(); // 180
};
