[rrd-users] Re: Local time zone

[Chitman Kaur]

Hi
I am also using flowscan with JKFlow...
In the JKGrapher.pl... if we put $ENV{'TZ'} = "GMT"; in the beginning of the script then the timings of the graph comes in GMT....
Since you are using CampusIO then you need to search which file makes the graphs.... I think its graph.mf (I am not sure)... so put this line in the beginning of graph.mf (if that’s the file) .... 
You don't need to put it in pm files.... as far as I know changing to GMT or to any other timing should happen when we read the RRD to create the graph ….not when we put data into it.....

Hi,

thank you for a hint, I think that this trace is good but
for now I can't make it work - I tried GMT or CET time zone,
and result is the same (my data is one hour late).
I found this page:

http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/perlbind/RRDs.html

If you are manipulating the TZ variable you should also call the posixs 
function tzset to initialize all internal state of the library for 
properly operating in the timezone of your choice.

use POSIX qw(tzset);
$ENV{TZ} = 'CET';
POSIX::tzset();

and used this code - the problem is that my rrdfiles are feeded from
flowscan perl script, and I don't know if I implemented this TZ code
in right way inside its modules (CampusIO.pm). This is a big problem
for me, and any help will be appreciated.

Best regards,
Robert
