Moment.js not working with external javascript file

The error described below is reproduced here: https://jsfiddle.net/cxhvr3Lq/

---

I am using jQuery, bootstrap, moment, and my own javascript file myjs.js. I created a minimum example where my custom javascript is not working. The code in myjs.js is:

function adjust_times_user_time_zone() {      console.log(moment.tz("2015-08-05T00:00:00+01:00", "Europe/London"));  };    $(document).ready(function () {      adjust_times_user_time_zone();  });  

but this throws the following error, which is incomprehensible to me.

jquery.min.js:2 jQuery.Deferred exception: Cannot read property 'apply' of undefined TypeError: Cannot read property 'apply' of undefined      at h.utcOffset (https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.33/moment-timezone-with-data.js:664:15)      at Function.moment.updateOffset (https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.33/moment-timezone-with-data.js:623:9)      at h.fn.tz (https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.33/moment-timezone-with-data.js:638:12)      at Function.tz (https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.33/moment-timezone-with-data.js:568:7)      at adjust_times_user_time_zone (file:///Users/js/myjs.js:37:24)      at HTMLDocument.<anonymous> (file:///Users/js/myjs.js:41:5)      at e (https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js:2:30005)      at t (https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js:2:30307) undefined    jquery.min.js:2 Uncaught TypeError: Cannot read property 'apply' of undefined      at h.utcOffset (moment-timezone-with-data.js:664)      at Function.moment.updateOffset (moment-timezone-with-data.js:623)      at h.fn.tz (moment-timezone-with-data.js:638)      at Function.tz (moment-timezone-with-data.js:568)      at adjust_times_user_time_zone (myjs.js:37)      at HTMLDocument.<anonymous> (myjs.js:41)      at e (jquery.min.js:2)      at t (jquery.min.js:2)  

I am loading jquery, bootstrap, moment, and myjs in that sequence. Any idea what is wrong?
