<input type="time" />

The time input marks this element as accepting a string representing a time. The format is defined in RFC 3339 (opens new window) and should be a partial-time such as

19:04:39
08:20:39.04

Currently, all versions of Edge, Chrome, Opera, and Chrome for Android support type="time". The newer versions of Android Browser, specifically 4.4 and up support it. Safari for iOS offers partial support, not supporting min, max, and step attributes.
