I used wrong tracking id in my E-commerce tracking code for Google analytics and missed the data for few days.

To add that missing data in my account I have written a short script which manually send all orders data for four days to GA account but what my concern is date : Those orders which already placed on different dates and , when if I run my script and so it will send my missing data with current date , which I do not want. ( I want to send date when that order is actually placed)

do anyone help me with this ?

I am really much stuck with my work here.
