Convert datetime to include utc timezone php

I am trying to convert datetime to a UTC timecode using PHP, how do I convert 2022-05-14 13:30:30 so it will come out as 2022-05-14T13:30:30+01:00

Thanks

>Solution :

The format can be obtained with the method toAtomString(). With my timezone settings, i got the timezone 02:00, so i had to use setTimezone() and specifying the timezone on the parsing. Can be left out, if yours is correct.

Carbon::parse('2022-05-14 13:30:30', 'Europe/london')
    ->setTimezone('Europe/london')
    ->toAtomString();

This will format the date as follows 2022-05-14T13:30:30+01:00.
