Based on the original source code, it appears this should use longitude.
Second parameter should be utcOffset and third parameter should be Longitude.

Fixed. I've been trying different ways to achieve the same. Missed the readme. Thanks.

Is there a better way to handle the date object when it crosses between days? Using 23:58 as a starting time would be a good test.

I would recommend switching to a date object as the return.
return new Date(date.getTime() + timeCorrection * 60 * 1000);That will handle the above issue and allow the user to format the date however they want.

Works with any date and time, including seconds and milliseconds.

Thanks for the PR! Is there a reason to separately introduce this method if you can already get |

Hi @mourner, thank you for your time. The main reason behind the PR is that solarNoon is always the same for a given latitude and longitude (as stated, the sun's highest position). The solar time is a calculation of the passage of time based on the position of the Sun in the sky, which varies with the given date. If there's already a way to achieve this with the library, please let me know. I struggle a bit with the terms :) |
