Pattern

regexJS
(?:0?[1-9]|1[0-2]):[0-5]\d(?::[0-5]\d)?\s?[AaPp][Mm]   (flags: g)

JavaScript / ECMAScript code

jsJavaScript
const re = new RegExp("(?:0?[1-9]|1[0-2]):[0-5]\\d(?::[0-5]\\d)?\\s?[AaPp][Mm]", "g");
const input = "9:30 AM";
const matches = [...input.matchAll(re)];
console.log(matches.map(m => m[0]));

Uses `String.prototype.matchAll` for global iteration (Node 12+ / all modern browsers).

How the pattern works

Hour alternation covers 1–12 (optional leading zero), minute/second classes enforce 00–59, optional whitespace separates the AM/PM suffix. Case-insensitive AM/PM via character classes.
