What Is a Timestamp and Why Is It Necessary?

Under Electronic Signature Law No. 5070, a timestamp is defined as "a record verified with an electronic signature by an electronic certificate service provider in order to determine the time at which electronic data was created, changed, sent, received and/or recorded."

Simply put: a timestamp is used to prove that a document, record or contract existed before a certain time. It can be used on any electronic application, report or contract that needs time information.

Where Is It Used?

• In all e-Government applications such as e-Ledger (e-Defter), e-Invoice and e-Archive
• In EDMS (Electronic Document Management Systems), to prove a document's integrity and that it existed on that date
• In proving intellectual property / copyright, to end "this is my work" disputes by proving that a script, code or design was in your possession on a certain date
• In electronic contracts, to record the moment of signing beyond dispute

How Do I Buy It?

Timestamps are not sold as an annual subscription but as quantity-based packages with no time limit; you can use them until the quantity you bought runs out. Through eimzahemen you can choose the package that suits you from 1,000, 10,000 and 100,000 units and apply within minutes.
