I want to find the delete all the string after the 19:11.. so the string will be only

You can use a capture group to get what you want

check out this pattern (\w.+\d):

Instead of removing things from the string, you can pick out the part that you want:

var time = 'Sun-Sep-20-2015-19:11:53-GMT+0300';

var date = /^(.+?-.+?-\d+-\d+)/.exec(time)[0];

// show result in snippet
document.write(date);

You can use a capturing group:

var str = 'Sun-Sep-20-2015-19:11:53-GMT+0300';

var result = str.replace(/^(.+?\d{4}).*$/m, '$1');
