sum two date

[Cesar Amores]

is possible sum two date in jira automation?

NewTimeInWaiting op: {{issue."Start Time in Waiting"}}
NewTimeInWaiting: {{NowTimeInWaiting}}
starttimemillis: {{issue."Start Time in Waiting".millis}}

Total: {{issue."Start Time in Waiting".plusMillis(issue."Start Time in Waiting".millis})}}

Hi @Cesar Amores -- Welcome to the Atlassian Community!

What problem are you trying to solve by doing this, as summing two date fields does not make sense to me?

Instead is one of the fields a date/time field and one of them a number field of time units?  If so, you can add the number to the date/time field by using the plus functions as you have shown: https://support.atlassian.com/cloud-automation/docs/jira-smart-values-date-and-time/#Example.6

Kind regards,
Bill
