Convert timestamps to localtime

[asyncmind0]

Would t be possible to convert the @timestamp field to local time. Kibana seems to be doing this by default

I think it should be possible to add that feature. I suppose there could be an option to use local time and if that option is used then:

• timestamp field would be displayed in local time
• date range filtering would also work in local time unless zone is specified in dates themselves
• logic for finding appropriate indices would also need to be adjusted when date filtering happens in local time

I'll take a look and see is it feasible to add this quickly.
