+ * ConvertTzFunction
+ * Description: CONVERT_TZ(string1, string2, string3)--Converts a datetime
string1 (with default ISO timestamp format
+ * ‘yyyy-MM-dd HH:mm:ss’) from time zone string2 to time zone
string3. The format of time zone should be
+ * either an abbreviation such as “PST”, a full name such as
“America/Los_Angeles”, or a custom ID such
+ * as “GMT-08:00”.
+ * for example: CONVERT_TZ(‘1970-01-01 00:00:00’, ‘UTC’,
‘America/Los_Angeles’) returns ‘1969-12-31 16:00:00’.
