timezone.js | Bare minimum version of Moment Timezone without dependencies | Date Time Utils library

I am using Fullcalender Scheduler V5. I added calendar.refetchEvents(); at the end of eventDrop, eventResize, eventClick also. It is working well. But when I use it in other functions to add /edit the events, it is not working.Here is my code:

i'm building an hybrid angular app and i have a problem with my dropdown menu. It doesn't open, instead, it redirect me. I think the dependency are loaded in the correct order. I'm using bootstrap 3.1.1 and jquery 2.1.3. This is the html code i refer to:

I am having quite a fight with a Tomcat 6 (on CentOS 7.6) which is behind a HAproxy 2 (on CentOS 7.7), maybe someone can help me.

I want my users to put on the web browser something like http://myapp.mydomain.com this will resolve HAProxy IP, where it will be taken and forwarded to http://TomcatIP:Port/some/path/tofile (single server in the back end, no balancing yet). It seems to be configured correctly, because when I put the simple URL on the web browser, the favicon and title of myapp appear, but the rest of the page is kept blank (white with nothing on it, no error, nothing). I know there are other ways to accomplish this without involving HAProxy, but this is a prove of concept, to start using it as a frontend for more sites and using loadbalancing.

This is my HAProxy.cfg:

I need to convert datetimes from an input format which I can't change (this: "Tue, 30 Jul 2019 21:15:53 GMT") to UTC, in Javascript.

I actually need to get these dates as the number of milliseconds since the Unix epoch (1970) but getting in UTC would be a start.

Is there a way to do this easily? I can use a 3rd party library if needed. I've heard of moment-timezone.js but not clear how to parse the 3 letter timezone, i.e. these: https://en.wikipedia.org/wiki/List_of_time_zone_abbreviations.

Try to read json file from another directory in React for options of react-select. It doesn't matter when writing json in the same file, but it doesn't work when reading from another file because it includes number of array.

This works:

sam local invoke -t template.local.yaml -e events/event-timezone.json GetTimezoneFunction

This does not work when trying to debug with Visual Studio Code:

sam local invoke -t template.local.yaml -e events/event-timezone.json -d 5858 GetTimezoneFunction

The difference is that, in the second, I get an error that the npm 'axios' module, which is defined in a separate layer used by my lambda function, is not found.

How can I find a random location based on the moment-timezone.js? I want to show a new location every time you refresh the page.

Current code:

I have some json data related to timzone below i need to bind particular nested value into dropdown, in using angularjs, in timezone array its coming as string format i need to bind those into dropdown.

Trying to create a .ics file which has a VTIMEZONE component, which based on the supplied timezone sets the Standard time and Daylight Savings time dynamically.
