Hi!

Im very new to Node-Red and are trying to create a function.

My code looks like this:

let startDate = new Date(2022,8,7,0,0,0,0);

node.warn(["your\_variable=", startDate]);

the debug log output is this:

2022-09-06T22:00:00.000Z

While im expecting it to be 2022-08-07T00:00:00.000Z

Im using Home assistant OS on a Raspberry Pi 4 and the location settings are correct.

Any idea?  
Thanks in advance!

Hi @Draax

The `new Date(...)` function expects a `monthIndex`, which starts at `0` for January. So passing in an `8` as you are, actually means September.

As for the hours - the function creates the time in the timezone of the device its running on. If you are passing in `00:00:00` as the time, the fact it results in `22:00:00Z` suggests you are in a `GMT+2` location.

Hi @knolleary,  
Much appreciated for your feedback!

I understand the month index part but if possible could you please provide me an example of how I could achieve creating a starting date of today with the hours 00:00:00?

Do you want midnight local time or midnight UTC?

Your new Date (2022, 8, 7, 0, 0, 0, 0); What you get is a Date instead of a str and your time zone ratio is +2. It is recommended to use moment to solve it. This module is very powerful

It seems that @Draax has lost interest in the question.
