[Observium] Strange timezone behaviour in graphs

Hi,

I'm not sure what to make of this. When I try to enter custom time ranges in any of the traffic graphs, I get different results depending on which browser I'm using.

Results are as follows. I'm in Brisbane (GMT +10).

Mac OS X 10.6

Firefox: Observium always converts the time I enter (in local time) to GMT. Therefore my graphs are out by 10 hours. Safari: Won't accept any time info I enter. Always give me the last 24 hours. Chrom: Everything seems to work ok.

Windows 7

Internet Explorer: Always gives me the last 24 hours. Same as Safari on OS X Chrome: Everything seems ok.

Clicking any of the preset time periods, e.g 6 / 24 / 48 hours, always works ok regardless of which browser/os I'm using.

Is this expected behaviour?

Cheers, Matt.
