[rrd-users] Re: Thinking too hard?

[Tobias Oetiker]

Yesterday you sent me mail regarding [rrd-users] Thinking too hard?:

*>  I'm trying to do something that seems natural to me but I can't figure
*> out if it's supported by RRDTool or not.
*> 
*>  Basically, I have lots of measurements that I want to display to users
*> as graphs on web pages. (Sounds like an excellent fit so far...) Since I
*> have no good idea which pieces of data they may want to see and since
*> the data is constantly updating, I am planning to dynamically create the
*> graphs based upon their requests (still a good fit...)
*> 
*>  The part that I'm less sure of is time zone. The users will be in
*> locations across the globe and I'd prefer to generate the graphs with
*> the time scale based upon their local time zone. I know that the
*> observations within the database are basically in GMT already and that
*> in Javascript I can find the user's current offset from GMT, so I think
*> I have all of the raw information I need. I'm not sure that this is
*> provided for in RRDTool however. 
*> 
*>  I have looked through the documentation as well as the list archives
*> and didn't find anything that tells me how (or if) this is possible. A
*> walk through the source shows only about ten references to 'localtime',
*> so such a thing would not be unmanageable even if it is not already
*> there. 
*> 
*>  Did I miss something here? Is this feature planned? I'd be more than
*> willing to take a crack at this myself but I don't want to re-create
*> something that's already there or planned as a coming feature.

if you are using rrdcgi to generate the graphs you can use the SETENV
function to set the value of TZ to the name of the useres local timezone ...
