from haystack docs:

Ranges are exclusive of start timestamp and inclusive of end timestamp. The {date} and {dateTime} options must be correctly Zinc encoded. DateTime based ranges must be in the same timezone of the entity (timezone conversion is explicitly disallowed). Date based ranges are always inferred to be from midnight of starting date to midnight of the day after ending date using the timezone of the his entity being queried.
