Choose "Local Time" to automatically detect your timezone. You may need to manually specify if you're using a proxy.
Hint: Remember the 'S' in timezone names changes to 'D' during daylight savings (e.g. PST > PDT).
'Overlaps' shows results that at least partially overlap with the period you've selected whereas 'Begins Within' will only show events that completely fit within it.
