Can't get UTC output to work

[mountaindude]

Having read the docs, my understanding is that I can call later.date.UTC() to make the occurrences I create to be in UTC. UTC should even be the default.

But no matter what I do I just get local time zone... The code snippet below prints current time as UTC to the left and the occurrences from later to the right. I am basically trying to get later output something without a timezone offset applied.

const later = require('@breejs/later');

const sched = later.parse.text('every 5 minutes');
later.date.UTC();

const s = later.schedule(sched);
const occurrences = s.next(5);

const utcDate = new Date(Date.now());

console.log('-------------------------------------------------------------------------');
for (let i = 0; i < 5; i++) {
    console.log(`${utcDate.toUTCString()} /// ${i + 1} /// ${occurrences[i]}`);
}

results in this:

➜ node index.js
-------------------------------------------------------------------------
Thu, 21 Oct 2021 18:56:00 GMT /// 1 /// Thu Oct 21 2021 21:00:00 GMT+0200 (Central European Summer Time)
Thu, 21 Oct 2021 18:56:00 GMT /// 2 /// Thu Oct 21 2021 21:05:00 GMT+0200 (Central European Summer Time)
Thu, 21 Oct 2021 18:56:00 GMT /// 3 /// Thu Oct 21 2021 21:10:00 GMT+0200 (Central European Summer Time)
Thu, 21 Oct 2021 18:56:00 GMT /// 4 /// Thu Oct 21 2021 21:15:00 GMT+0200 (Central European Summer Time)
Thu, 21 Oct 2021 18:56:00 GMT /// 5 /// Thu Oct 21 2021 21:20:00 GMT+0200 (Central European Summer Time)
➜

Meh - that was literally less than a minute from posting to realising that this works:

for (let i = 0; i < 5; i++) {
    console.log(`${utcDate.toUTCString()} /// ${i + 1} /// ${occurrences[i].toUTCString()}`);
}

Still, from reading the docs I still expect that later.date.UTC() would give me UTC straight from later...

Oh well - all good I guess :)

you need to call later.date.UTC() before any other later calls.

Ok, but this code gives the same result as above, and I can't really move later.date.UTC() any higher up..

const later = require('@breejs/later');
later.date.UTC();

const sched = later.parse.text('every 5 minutes');

const s = later.schedule(sched);
const occurrences = s.next(5);

const utcDate = new Date(Date.now());

console.log('-------------------------------------------------------------------------');
for (let i = 0; i < 5; i++) {
    console.log(`${utcDate.toUTCString()} /// ${i + 1} /// ${occurrences[i]}`);
}

I figured it out, two things later will will return a Date object which mean that when it is stringified by default it will be displayed with local time offset.

and later.date.UTC makes later parse all dates as UTC. I.e.

later.date.UTC();
// system currently set for CST
const sched = later.parse.text('every Monday at midnight');

const s = later.schedule(sched);
const next  =  s.next();
// `next` when stringified will be offset by 5 hours from midnight
// but `next` will actually be midnight UTC

Ahhh... nice. Gottit.

Many thanks!
