DateTime value sent via REST API is not set correctlyIssue When you update or insert a DateTime field using REST API, the value that is saved might be different from what was sent. You can see the DateTime value gets saved in the UTC timezone.Causesysparm_input_display_value is not set to true for the REST API requestResolutionREST API stores the date-time in the UTC time zone unless you specify sysparm_input_display_value to true. If you specify sysparm_input_display_value to true, then the date-time is stored exactly what you sent in the request. If not, the date-time sent via REST API is converted to the UTC time based on the User's timezone(User initiating the REST call) If the User's time zone is not set then the system time is taken for reference to convert to UTC.Related LinksPlease refer - What is the equivalent of "sysparm_input_display_value" for Change management API for implementing this solution in Change management API
