fmt:formatDate and timeZone

I have fields in a Mysql database typed datetime.

I store, for example, a payment's date with next Java code:

payment.setCreatedOn(new Date(System.currentTimeMillis()));

In my view layer I use fmt:formatDate to format dates:

<fmt:formatDate value="${payment.createdOn}" pattern="EEE, dd MMM yyyy HH:mm:ss"/>

My server is in London and my application's users are in Vienna. The time showing is delayed probably because of different time zones. I can use a timeZone Parameter in fmt:formatDate.

timeZone: Time zone in which to represent the formatted time.

After searching in Google, I think the value Europe/Vienna is valid for timeZone parameter.

Does anyone knows if there is list anywhere of the valid timeZone strings?

You need to use the international time (UTC/Zulu) to add the following schedule client time use, for example "GMT+1". See this example.

Put this parameter as argument in your server to set UTC time use, in this case is for tomcat:

-Duser.timezone="UTC"

/* Java */      

@RequestMapping(value = "/web", method = { RequestMethod.POST, RequestMethod.GET })
public String web(Model model, HttpSession session, Locale locale) {

    Date today = new Date();
    model.addAttribute("currentTime", today);
    model.addAttribute("timezone", "GMT+1");

    return "web";
}

To show date choose your pattern you want (properties)

/* JSP web */

<fmt:timeZone value="${timezone}">
<spring:message code="date_format_dateMin" var="pattern"/>
<fmt:formatDate value="${currentTime}" timeZone="${timezone}" pattern="${pattern}" var="searchFormated" />
<span class="innerLabel">${searchFormated}</span>   
</fmt:timeZone>

/* Properties */

date_format_dateMin=yyyy/MM/dd HH:mm
date_format=yyyy/MM/dd HH:mm:ss    
date_format2=yyyy/MM/dd
date_format3_js=yy/mm/dd
date_format4_time=HH:mm
date_format4=dd/MM/yyyy HH:mm:ss
