The GMT standard time, ie Greenwich Mean Time (GMT+0 or UTC+0 or Zulu time) is included in the timestamp in the documents signed with an Evrotrust Certificate and in the signature placeholder at the bottom of the last page as well. On the placeholder this is indicated by a letter Z (Zulu), see below.

Adobe Reader recognizes the user's location, converts and displays the time of the e-signature according to the user's current time zone. It will then place after the date and time which time zone the date and time was displayed. E.g. 2021/01/19 14:09:34 +01: 00 (so this time is in GMT+1).

Checking the date and time of an e-signature is simple: in the Adobe Reader click on the placeholder and then the signature properties to view the time of the e-signature in the signed document.

Evrotrust e-signatures have a visible signature placeholder (looks like a watermark) at the bottom of the last page of the document, which also contains the signature date and time.


However, this always shows the time in GMT+0/UTC+0/Zulu time, because the placeholder is an image and so its content cannot change dynamically according to the time zone in which the PDF is opened. Therefore, opening the signed document e.g. in Hungary the placeholder displays the date and time an hour earlier (Hungary is in GMT+1 time zone).
