I am trying to get time and date in my local timezone (UTC-3) from a string timestamp (ex "1612909488"). I was looking for a solution in C++ but each example or code i saw only got the time and date from timestamp without applying the local timezone. For example if the timestamp is "1612909488" then UTC time is 22:24:48 but I need it in my local timezone that is 19:24:48. How can I do that?
Thanks for your help.
