World time...

[visitor]

Hi

 

I've got the below script which works almost perfect... the only thing I'd like to have changed is an automatic update on summer and wintertime. Does anyone know how this can be done, please?

 

<table style="width: 100%; height: 100%;"> 
  <tr> 
   <td valign="middle" align="center"> 
    
    <script language="javascript1.2">

// get the date and change it to GMT string

var date = new Date();

var timegmt = date.toGMTString(); 

// split the GMT string at spaces

time_string = timegmt.split(' '); 

// assign variables

week = time_string[0];

day = time_string[1];

mon = time_string[2];

year = time_string[3];

hms = time_string[4]; 

// split the time part on colon

hms_string = hms.split(':'); 

// assign variables

var hour = hms_string[0] - 0;

var min = hms_string[1]; 

// convert day-of-week variables to numbers

if (week == 'Sun,') {

    week = 1

    }

if (week == 'Mon,') {

    week = 2

    }

Daylight Savings

 

i am sure you can modify that to include DST(daylight savings time) in your own function
