It would be a helpful basic feature to not have to look at times in zulu, I suggest a time offset with intelligent daylight savings time based on location of user.

Yes, I agree. At the moment the data that you see in charts will be in US Pacific Daylight Time (we are located in Palo Alto, CA). The data that you see in search results will be in the native timezone that the data was collected in (which is usually zulu or your local time).

We plan to add a timezone configuration that allows users to choose their own timezone so that charts and results are adjusted to show in your local time.
