Best practice for timezones in invoices?

Hi all,

Whats best practice in terms of timezones on invoices and other business documents?

Scenario:

A US based company invoices a European company at 11pm EST on April 30th. Thats actually 5am CET on May 1st in Europe. Some European companies have payment terms stating that an invoice will be paid "at the end of a month plus thirty days". 

I am assuming that it is the timezone of the sender which counts and that you would not "normalize" the view of an invoice to your own timezone.

Best regards,
Mikkel
