A timestamp is an electronic record that keeps track of all transactions and approvals occurring in a digital environment. It is recorded through a computer, ensuring its integrity and proving its existence at a specific date.

According to Article 3, paragraph (h) of Law No. 5070 on Electronic Signatures (In Turkish), a timestamp is defined as "an electronically verified record with an electronic signature, provided by an electronic certificate service provider. Its purpose is to determine the time when electronic data is produced, modified, sent, received, and/or recorded."

Although GDPR is a text that pursues and adopts the main principles stipulated by Directive 95/46, it has been introduced some regulations to be more compatible with today's requirements intended for the new needs arising from the latest technologies.¹ However, the concepts of "consent" and "explicit consent" which are the elements that provide legal legitimacy for the processing of personal data in Directive 95/46, and the terminology that created within the framework of these concepts, continued to be used in the EU General Data Protection Regulation. It is required that consent must "unambiguously" given in Directive 95/46. In case of the processing of personal data, it is stipulated that the condition of explicit consent is required. The conditions for the validity of the consent are also regulated in Article 4 of the EU General Data Protection Regulation. The elements specified in this Article provide the validity of both types of consent.
