What exactly is a timestamp?

Do you sign with Adobe or similar tools assuming your signatures are valid?
Countless professionals sign documents each day assuming they are legally watertight, until a judge or specialist questions either the authenticity or the timing of the signature
It can be tampered with
A device’s internal clock can be altered at any moment, leaving no technical evidence that would stand up in court.
It carries no evidential value
Only a qualified timestamp can verify the precise signing moment and provide full legal validity.
What if I sign with a digital certificate?
An FNMT digital certificate confirms who signed, but not when the signature was applied.
Without a qualified timestamp, the date shown comes from your device, can be altered and carries no meaningful evidential strength. Your documents may be rejected or require additional verification.
