Question

I am working on facebook integration in my application.

Facebook returns users timezone in the format like for India its

5.5

But the existing timezones are saved in database in format

 +05:30

Any functions or algorithm suggestions for this conversion.

thanks .

Answer 1

This one is a bit long but it adds necessary preceding zeros etc if that’s a requirement.

$num = -5.5;
$res = ($num < 0 ? '-' : '+') . (abs($num) < 10 ? '0' : '') . abs((int)$num) . ':';
// --> -05:
$mins = round((abs($num) - abs((int)$num)) * 60);
// --> 30
$res .= ($mins < 10 ? '0' : '') . $mins;
echo $res;
// -05:30
