### Version

### Describe the bug and provide the minimal reproduce step

The core issue lies in org.apache.iotdb.db.utils.datetimeutils.DateTimeUtils.toZoneOffset(ZoneId zoneId). This method calculates the timezone offset using Instant.now(). In regions that observe Daylight Saving Time (DST), such as Europe/Warsaw, the offset is not constant throughout the year (+1 in winter, +2 in summer).
timezone: Europe/Warsaw
INSERT INTO root.test.d1(time, s1) VALUES(2024-01-01T00:00:00, 1);
SELECT s1 FROM root.test.d1;
