edit scheduled date custom field(date and time field) from scheduled date text in the issue descript

[Gomez, Daniel]

In Jira automation, Is it possible to update a date and time field from a date and time found in the description? Ive tried several different ways and the closest I got was the date right but the time will be off 

create variable action: {{issue.description.match("(\d{1,4}([.\-/])\d{1,2}([.\-/])\d{1,4})")}}

edit issue action: {{ScheduledDate.toDate("MM/dd/yyyy").plusDays(1).plusHours(1)}}

I tried advanced json:

{
"fields": {
"customfield_10000": "2023-11-02T14:00:00.000+0000"
}
}

this works but gives me the exact date and time entered instead of whats in the description
