This one will do the trick as well. Convert hex to int by calling parseInt with radix argument 16:

var time = new Buffer('506BF1E3','hex');
console.log(parseInt(time.toString('hex'), 16));

Use this? Seems much better than parsing...

time.readUInt32BE(0)

However, I think you need to make sure that this is always 4 bytes (32-bits), otherwise it will fail.

this will do the trick:

var time = new Buffer('506BF1E3','hex');
console.log(parseInt("0x"+time.toString("hex")));
