Thanks for providing the solution. I am a non-coder, so let me explain what I understood from your reply.
For example, if the job posting's last date is 13th December 2022, for a position in the USA. Since I am posting it from India, first I need to recalculate what would be date and time in India and the date and time should be entered as such. But, because I have opted for 'save time value as time stamp', even after me adding the last date according to India time, for a user viewing from the US would be accurate. because the option calculates the difference and shows the modified time.
Did I get it right?
now the question is, does this calculation get affected by VPN?
another question: is there any way to show a countdown timer based on this value?
