A custom function sharing _php instance in PHP that converted American time to Beijing time

As a result of the recent mail system to use the time conversion, the need to download the mail from Google Gmail time into Beijing time, and then wrote a time conversion function, I hope to have the need for all the inspiration, we know the time difference between China and America 13 hours, the following directly on the code:

function Datezhuanhuan ($dateparams)
{
$CCC =strtotime ($dateparams);
$date =date (' y-m-d ');
$bjtime =date (' y-m-d ', $CCC);
if ($date = = $bjtime)
{
$sbjtime =date (' y-m-d h:i:s ', $CCC);
Echo substr ($sbjtime, 11,5);
else
{
$sbjtime =date (' y-m-d h:i:s ', $CCC);
Return substr ($sbjtime, 5,5);
}

Another + 8-hour algorithm:

$BJ _time = Date ("y-m-d h:i:s", Mktime (gmdate (' H ') +8,gmdate (' I '), gmdate (' s '), Gmdate (' m '), Gmdate (' d '), Gmdate (' Y '));
