在php中从时间戳获取时间

Question

I am using Forecast.io weather api to get weather data. I have a little problem while i display sunrise and sun set time of that location.

it give time in time-stamp format also provide offset hour difference so i did following code to get time

//following GMT value or offset get from api
$offsetHours = '-5 hours';
// This time i get from api
$currentValue = '1401705628'; 
$actualTimeStamp = strtotime($offsetHours,$currentValue);
echo $actualTimeStamp;
echo date('h:i A',$actualTimeStamp);

Last echo time is actual time that is '5:40 AM' i got but in some php version it gives wrong result.

so is there any other way to doing this i cannot update my php version

Answer 1

date('h:i A', (time()-(60*60*5)));

Answer 2

gmdate('Ymd H:i:s', strtotime ('+1 hour')) you can be as flexible as you like with how many hours you want to go forward or back ie(- 1 hour). But have to use strtotime PHP function :)

Answer 3

Have you tried using the \\DateTime Object of php? Try something like this:

$currentValue = '1401705628';
$offsetHours = '-5 hours';

//Create DateTime Object With Date = NOW()
$date = new \DateTime();

//set Timestamp to DateTime Object
$date->setTimestamp($currentValue);

//Its the date from the timestamp
echo $date->format('h:i A') . '<br><br>';



$pattern = '/^([\+|\-]?)(\d+)\s(hours|hour|minutes|minute)$/iU';
$match = array();

if (preg_match($pattern, $offsetHours, $match)){
    //$match contains an array of matching elements of the pattern
    // $match[0] = '-5 hours'
    // $match[1] = '-'
    // $match[2] = '5'
    // $match[3] = 'hours'

    //Creating the DateInterval String
    $intervalStr = 'PT' . $match[2] . strtoupper(substr($match[3], 0, 1));
    // Create an object of the DateInterval
    $dateInterval = new \DateInterval($intervalStr);

    if ($match[1] === '-'){
        //Substract the DateInterval from Date
        $date->sub($dateInterval);
    }
    else {
        //Add the Dateinterval to date
        $date->add($dateInterval);
    }
} //if preg_match


//Its the date with the offset
echo $date->format('h:i A');

EDIT:: I've updated my example to resolve the time offset dynamically
