Thanks for the information. <div><br></div><div>It does make sense that everything would be related to UTC. I don't really want to fudge the time zone info here and you mentioned "<meta http-equiv="content-type" content="text/html; charset=utf-8">If you want a period other than that you will need to keep a more detailed set of data and do things slightly differently." Please explain.<div>
<br></div><div>Also, if a data source is GAUGE then "<span class="Apple-style-span" style="font-family: sans-serif; border-collapse: collapse; line-height: 24px; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px; ">These are "real" values so they should match what we put in"</span> the rrd. If the source of data is an accumulation ie. total number of cars past a certain point with respect to time, then the data will reflect just that. In this particular case I am not measuring rate. </div>

</div>RRD Tool **ONLY** stores rates. You can calculate total from the rate<br>
very easily.<br>

<br>
</div>RRD Tool references everything to Unix Epoch - ie Midnight 1st Jan<br>
1970 UTC. If you have a 24 hour consolidation then it will ALWAYS<br>
start and end at midnight UTC. If you want a period other than that,<br>
you will need to keep a more detailed set of data and do things<br>
slightly differently.<br>
<br>
Alternatively, you could fudge it by setting the timezone to UTC<br>
before doing each update and before doing each extraction. Ie, make<br>
RRD Tool think that the times you are feeding it are UTC rather than<br>
your real local timezone.<br>
