Trigger Reminder Formula

[NP]

Hi,

Would like to set up a Trigger Reminder with the formula;

IF(
AND(
{Reminder},
NOW() >= {Reminder}
),
"Trigger Reminder"
)

But instead of NOW, would like to customized it to xx hours from created TIME, specifically. Have only seen customize formulas for a certain date or number of days but nothing for a certain time period. 

Any help would be greatly appreciated.

If you have a field with the Created Time already made you could try this:

DATEADD({Created Time}, XX, 'hours')

instead of

NOW()

Dunno if this is what you're looking for?
