Jiffy difference

[rakakhrl]

Hey jama, i just want to ask one question about the difference method. In the documentation u said that when we look for difference from this

Jiffy({ "year": 2007, "month": 1, "day": 28 }).diff([2017, 1, 29], Units.DAY); // 1

It return 1 day

My question is shouldn't it return 3651 days instead? because its 10 years and 1 day apart

Hi, @rakakhrl . I have tried this and it works fine. I tried the following

Jiffy({ "year": 2007, "month": 1, "day": 28 }).diff([2017, 1, 29], Units.DAY) // -3654

and also

Jiffy([2007, 1, 28]).diff([2017, 1, 29], Units.DAY) // -3654

Or maybe I haven't understood your question correctly

@rakakhrl I understood your issue. The docs shows the wrong output on the section you have said.

difference

it's supposed to be both to have the same year which is 2017

Jiffy({ "year": 2017, "month": 1, "day": 28 }).diff([2017, 1, 29], Units.DAY); // 1

You could send a PR to fix it if you would like to contribute

Why does this output 0, shouldn't it be 1?
Jiffy({"year": 2020, "month": 3, "day": 29}).diff([2020, 3, 30], Units.DAY)

This is the only day that shows 0, for example this one is correct, outputs 1:
Jiffy({"year": 2020, "month": 3, "day": 28}).diff([2020, 3, 29], Units.DAY)

Also local time now has 1 hour difference

@jaykovski I have tried both
Jiffy({"year": 2020, "month": 3, "day": 29}).diff([2020, 3, 30], Units.DAY)
and
Jiffy({"year": 2020, "month": 3, "day": 28}).diff([2020, 3, 29], Units.DAY)

And they both return correct results which should be -1 not 1 or 0

If you would like to return 1, then just switch them in position, see example below

Jiffy([2020, 3, 30]).diff({"year": 2020, "month": 3, "day": 29}, Units.DAY) // 1

I also tried on local and utc, both return correct results

Or have I not understood your question?

[jaykovski]

The
Jiffy({"year": 2020, "month": 3, "day": 29}).diff([2020, 3, 30], Units.DAY)
returns "0" for me

and

Jiffy({"year": 2020, "month": 3, "day": 28}).diff([2020, 3, 29], Units.DAY)
returns "-1" (which is correct)

Hint: there was a daylight saving time on 29th

@jaykovski This may be related to #81, so I will close this issue for now since the docs have been corrected in difference
