@Godwin Dan
It's not possible to find out your exact location without using a 3rd party database. And all these service providers would allow only a limited number of requests per day/per month/etc. - otherwise they'll want you to pay.
Timezone 1.2 comes with a different solution which isn't that precise, but will lead you to the first city which is located in your own timezone.

Dear Sir, ~Z~ Man,

thank you for politeness and nice explaining. :)
Blessing to you!
I love Ossn very much, and this little unpleasant moment cannot change my good mind about your team as high and great professionals.

Respectfully and with friendly love,
Esther

@Z Man, I was inquiring about setting the default time zone on my end. Sure enough they can't be a default timezone for everyone round the world.

@Godwin
As Ossn is being used all around the world: What please should be the DEFAULT timezone?

Hi. Is there a way to select a default time zone. Should users don't go through the stress of searching the correct time zone?

Sorry Esther, no way.
Because the displayed timezones are not part of Ossn.

Try to address your issue to the PHP commnunity or the vendor of your operating system.
Good luck.

Dear Sir,

the right modern name of the our Ukrainian State Capital is "KYIV" but not "Kiev". "Kiev" it is into Russian, but we are other own National Independent state but not a Russian colony.
Correct, please, this very unpleasant mistake and
my future thanks to you and respect you for future correction.

With hope,
Esther from Ukraine
