Cannot get it to work

[laurax1981]

Hi all,
I am trying to use the datepicker in my website but cannot get it to work. I am including all these libraries:
'moment.min.js', 'moment-with-locales.min.js','timepicker.js','daterangepicker.js', 'daterangepicker.timesupport.js',.
Then I have a simple input tag <input id="date1" /> and a jQuery call $("#date1").daterangepicker();
and nothing shows up, except a TypeError: n.tz is not a function error in the console.
Any help?
Thank you.
