SlimStat can show hits and visits in your local time.
To do this, look for these lines in _lib/config.php:
/** Timezone */ var $timezone = 'Europe/London';
The $timezone field can contain any timezone supported by PHP. For a full list of these, see the PHP manual.
For example, if you are in New York, use the America/New_York value, like so:
/** Timezone */ var $timezone = 'America/New_York';
SlimStat will automatically adjust for daylight savings time, if your locale uses it.
