Get milliseconds from epoch via HTTP

I have a site called Current Millis and theoretically infinite bandwidth. I think i can quickly write a php, say www.currentmillis.com/api/millis-since-epoch.php. Is this ok for you?

UPDATE: It was infinite bandwidth but not infinite resources.. Because the server can not hope to sustain millions of HTTP requests to a service that resolves time to the millisecond, that URL has been discontinued.. Instead minutes since epoch are offered now: http://currentmillis.com/time/minutes-since-unix-epoch.php (because within 1 minute the value can be cahced by the host server)
