With either one, your app would carry some form of the tzdata with it.

Thanks for mentioning that. Although tz-link.html already mentioned 
Moment-Timezone, the timeZone option of JavaScript's Intl.DateTimeFormat is also 
worth mentioning as it can be a string like "America/Los_Angeles". I added the 
attached proposed patch to the development sources.

It seems that pretty much every JavaScript runtime except Internet Explorer 
supports tz names in the timeZone option nowadays, though older versions of 
runtimes may lack this support. See:
