const ALPHABET = "abcdefghijklmnopqrstuvwxyz0123456789_";

function encodeTimestamp(num) {
    let encoded = "";

    while (num &gt; 0) {
        encoded = ALPHABET[num % ALPHABET.length] + encoded;
        num = Math.floor(num / ALPHABET.length);
    }

    return encoded;
}

function decodeTimestamp(encoded) {
    let decoded = 0;

    for (let i = 0; i &lt; encoded.length; i++) {
        let charIndex = ALPHABET.indexOf(encoded[i]);
        decoded = decoded * ALPHABET.length + charIndex;
    }
