beforeDateTime and tzoneOffset

[AlexanderSk]

Hello,

I can you please check, support the option tzoneOffset along beforeDateTime.

Currently these two scripts show the exact same time.

$('#retroclockbox1').flipcountdown({
beforeDateTime:'10/20/2015 11:00:00',
tzoneOffset: 2
});

$('#retroclockbox2').flipcountdown({
beforeDateTime:'10/20/2015 11:00:00',
tzoneOffset: 3
});

I found a few time in order to fix it and i came with the following modification:
Line 187 options.beforeDateTime = Math.round((new Date(options.beforeDateTime)).getTime()/1000);

I placed for a test...

if(options.tzoneOffset){
//get current local time
var tmp = new Date(options.beforeDateTime).getTime();
//get current local time offset
var localoffset = new Date(options.beforeDateTime).getTimezoneOffset();
//find the difference between offsets
var offsetdif = ( (options.tzoneOffset * 60) + localoffset ) / 60;
//place the date in a var
tmp = (new Date(options.beforeDateTime)).getTime() - 3600000 * (offsetdif)
options.beforeDateTime = Math.round(tmp/1000);
}else{
options.beforeDateTime = Math.round((new Date(options.beforeDateTime)).getTime()/1000);
}

This covers the string and not the object case of course... but is is something :)
Unfortunately there is no easy way in javascript to convert a date into specific timezoneoffset.

Thank you for your time!
