Copy date field content to a datetime field without loosing the time

Question

Hi all,

I'm trying to build an automation which copies the time from a date field (Start Time) to a datetime field (Start Time [Gantt]).

When I do this the easy way, it will remove the time set in the datetime field and the requirement is to keep the time.

I can extract the time before making the change and put them into variables, called hours & minutes. But I can't add them to the datetime field.

I've an Edit issue component with Start Date [Gantt] (the datetime field) and the following smart value:

I also tried

{{issue.Start Date [Gantt].withHour({{hours}})}}

But I keep getting the error:

Error rendering smart-values when executing this rule:

Failed to get value for issue.Start Date [Gantt].withHour({{hours: {{issue.Start Date [Gantt].withHour({{hours}})}}
So how can I keep the time?

withHour is expecting a number, did you check your {{hours}} variable stores a number? (for example isNumeric()) Please share your automation rule. Thanks
