Multiple timezones displayed in confluence
Asked by Paul DeSousa:

We are a multi-national company and I am going through the possibility of having our default home page be confluence. Currently in our html default home page it will show each region's local time. I have tried to write a macro to do this but got stuck along the way. The following code will display the local timezone:

$action.dateFormatter.formatGivenString("HH:mm", $content.currentDate)

But I cannot figure out how to get it to display the various other timezones. I have seen that there is a tz parameter for dateFormatter but I could not find any examples of usage.

I was bored, so I decided to try it out. It's a bit of a hack and it's maybe not the easiest way to do it, but at least it works :smile:

body: Sorry where do you apply this? Do you need to create a new macro? edit the page in source editor? Sorry for the basic question, i'm pretty new to confluence.


author: Stephen Deutsch
body: Yes, you need to create a new user macro (You must be an administrator; click the Gear icon at the top of the screen, then General Configuration, enter your password, and find "User Macros" on the left side of the screen). You just give the user macro any name you want (no spaces) and a title (what will be displayed in the macro editor). If you want so that not everybody can see it, choose the visibility under the name. Everything else can stay blank/as it is. Once you save it, the macro should be available to insert on a page.


author: Paul DeSousa
body: What portions? Not sure I understand the question. Ideally I would want a macro that takes as a single parameter a time zone, and outputs the current time in that time zone. I have that all but I cannot find a good example of setting the timezone in dateFormatter.

body: For what portions of the page are you wanting this multiple time zone stuff on?


author: Paul DeSousa
body: Good point David! I guess I need to be more clear. I want to display the time. E.G.:CST: 13:45EST: 14:45CEST: 20:45KST: 04:48...

#set ( $hour = $calendar.get(11) )

body: What do you want to display in multiple times zones? Is it the create and modified date? Comments? Something within the page body? All of the above?
