[rrd-users] Showing daily average ; from midnight to midnight local time

[Jean-Yves Avenard]

I created a ticket to simplify the problem and not have to change the
TZ environment variable.

Adding a --utc option to rrdtool graph

I have migrated my set to use the rrdtool PHP module ; and changing
the timezone had nasty effect on apache, ... would mess up the log
files and other php applications I have running on the same machine
