ts-24hour.js

$(".TS-year_notch_year_text").each(function(){
  var el   = $(this);
  var text = el.text();
  text = text.replace(/(\d?\d:\d\d) ((a\.m\.|p\.m\.))/, function(date, time, ampm){
    var hourMinute = _.map(time.split(":"), function(it){ return parseInt(it, 10); });
    if(ampm === "p.m.") {
      hourMinute[0] = hourMinute[0] + 12;
    } else if(ampm === "a.m." && hourMinute[0] === 12) hourMinute[0] = 0;
    return hourMinute.join(".");
