Incorrect results for Pakistan

[Zulqarnain-Mustafa]

when i Pass the coordinates of "Pakistan, Faisalabad" it always return me "Asia/Kabul" where as it should me "Asia/karachi" as you can check via google api:
Faisalabad Coordinates

Result:
{
"dstOffset" : 0,
"rawOffset" : 18000,
"status" : "OK",
"timeZoneId" : "Asia/Karachi",
"timeZoneName" : "Pakistan Standard Time"
}

Where as APTimeZone Returns: Aisa/Kabul (GMT +4:30) offset 16200 It is wrong

Can you suggest any solution to this or fix this bug in APTimezone.
