javascript - Understanding momentjs timezones -

i'm using momentjs in project.

to current date , time in given format i'm using this:

moment().format('ddd, d mmm hh:mm'); // tue, 12 may 12:01 

if output , view in browser, see tue, 12 may 12:01. i'm in london utc+1. if did same florida, assume see tue, 12 may 07:01 (utc-4)?

my question

how can make sure views utc+1 time regardless of in world? think following way not sure.

moment().tz('europe/london').format('ddd, d mmm hh:mm'); // tue, 12 may 12:01 

hoping can explain.

yup, should work:

var = new date();    snippet.log("default: " + moment(now).format('ddd, d mmm hh:mm z'));  snippet.log("europe/london: " + moment(now).tz('europe/london').format('ddd, d mmm hh:mm z'));  snippet.log("america/new_york: " + moment(now).tz('america/new_york').format('ddd, d mmm hh:mm z'));
