I have Cacti installed on a server that has (and must continue to have) the Linux TZ set to UTC, but I want Cacti to record and present data using "US/Eastern".
I have set date.timezone = "US/Eastern" in all php.ini files and I observe that the Cacti poller is writing to the RRD files using US/Eastern as desired with the collected data appearing in the RRD file consistent with US/Eastern.
The problem is that the graphs are being rendered with the assumption that the current time of day is UTC, so there is always a four-hour empty gap in the graphs on the right hand side. Also in Cacti when I select a time range for a graph it interprets my request as being in UTC, so for example if I say I want "last hour" it shows up all empty since the last 4 hours on the graph are always empty.
Is there a way to work around this without forcing my Linux TZ to "US/Eastern"?
