Event Created with the Time of Event: 2019-10-16 04:00:23 Current Out-Of-The-Box functionality: If the data can be pushed by third-party integrator directly to ServiceNow Rest API in the ServiceNow format of the event, then the sender is able to build the request with all relevant event data in ServiceNow format including time in GMT time zone. For reference, please see "em_event.time_of_event" in https://docs.servicenow.com/csh?topicname=c_EMIntegrateRequirementEvent.html&version=latest2. If the data can't be pushed exactly in ServiceNow event format, then custom transform script should be defined and to perform there any required transformation (for example to reformat time_of_event field)https://docs.servicenow.com/csh?topicname=configure-listener-transform-script.html&version=latest Related Links<!-- /*NS Branding Styles*/ --> .ns-kb-css-body-editor-container { p { font-size: 12pt; font-family: Lato; color: var(--now-color--text-primary, #000000); } span { font-size: 12pt; font-family: Lato; color: var(--now-color--text-primary, #000000); } h2 { font-size: 24pt; font-family: Lato; color: var(--now-color--text-primary, black); } h3 { font-size: 18pt; font-family: Lato; color: var(--now-color--text-primary, black); } h4 { font-size: 14pt; font-family: Lato; color: var(--now-color--text-primary, black); } a { font-size: 12pt; font-family: Lato; color: var(--now-color--link-primary, #00718F); } a:hover { font-size: 12pt; color: var(--now-color--link-primary, #024F69); } a:target { font-size: 12pt; color: var(--now-color--link-primary, #032D42); } a:visited { font-size: 12pt; color: var(--now-color--link-primary, #00718f); } ul { font-size: 12pt; font-family: Lato; } li { font-size: 12pt; font-family: Lato; } img { display: ; max-width: ; width: ; height: ; } } To support the other time zone for the new API other than GMT, it is recommended to create an Enhancement Request to be able to review and possibly include in the future releases.
