Moment JS and convert to local time of user










0















Thought I understood how to convert a time stored in our DB to the users local time but seems I do not. When I save the kick off time into my postresql database (On Heroku) it is supplied as 2018-11-14 19:45:00, I save it as a TIMESTAMP. At the time i save it should I use moment?



Running Heroku logs I have noticed that the server time is 2018-11-14T19:45:00.200076+00:00, which is UTC ?



Using moment JS in my node app I am carrying out the following



fixture.kick_off = 2018-11-14 19:45:00.000000
<%= moment(fixture.kick_off).local().format('HH:mm A') %>


I have had a user from Denmark state that this is showing as 19:45 pm, where as i wanted it to show 20:45 PM as per the time difference



Have I misunderstood something here (very likely)



Thanks



Update



I am now using the below as per Matt's answer



<%= moment.utc(fixture.kick_off).local().format('HH:mm A') %>


Following on from Matt's comment around checking the typeof fixture.kick_off, it was returning object, have now updated my code to be



<% var kick_off = fixture.kick_off.toString() %>
<%= moment.utc(kick_off).local().format('HH:mm') %>


Which returns the following in the console



Deprecation warning: value provided is not in a recognized RFC2822 or ISO 
format. moment construction falls back to js Date(), which is not reliable
across all browsers and versions. Non RFC2822/ISO date formats are discouraged

          Assuming the time stored in your database based on UTC, you simply forgot to tell moment that. Use moment.utc(input) instead of moment(input)



          moment.utc(fixture.kick_off).local().format('HH:mm A')

          • Looking at your edit, the question is a but murky now. If the UTC time is 22:37, then the time in Denmark (UTC+1 on that date) would be 23:37, but you're asking for 20:45? Can you please clean up your question to be consistent?

          • Keep in mind that the UK isn't always aligned to UTC. It does UTC+1 for BST. But I don't think that's the source of your problem. Probably multiple things compounding here. I recommend doing some debugging and make sure that fixture.kick_off is really a string with a value like you showed here (you're missing quotation marks though - maybe you don't have a string but something else, like a Date object?)

          apologies, I have cleaned it up now, the Heroku server time is the same as here in the UK. If this question is still murky, happy to delete it and start again

          Keep in mind that the UK isn't always aligned to UTC. It does UTC+1 for BST. But I don't think that's the source of your problem. Probably multiple things compounding here. I recommend doing some debugging and make sure that fixture.kick_off is really a string with a value like you showed here (you're missing quotation marks though - maybe you don't have a string but something else, like a Date object?)
