In a authorized surroundings reminiscent of this, a easy timestamp is inadequate. It’s important in case your case hinges on proving that the signature’s timestamp is correct and that the doc was signed when it was claimed to have been signed.
As a result of it’s so simple to alter the date and time domestically on a machine, timestamps based mostly on system clocks are inadequate. As well as, a lot of on-line purposes allow you to alter the up to date, created, and most lately accessed dates of a doc or PDF. For instance, is the time stamp dependable?

Utilizing timestamping, companies can defend their mental property and provides auditable authorized proof. Learn extra.
Digital Signatures
Digitally signing a doc with a trusted timestamp ensures Lengthy-Time period Validation (LTV) and provides non-repudiation or confidence relating to the appliance time of the signature. As a result of digital signature affirmation entails an preliminary content material inspection, the significance of a timestamp is diminished in comparison with digital signatures.
Lengthy-Time period Validation (LTV)
It doesn’t matter if the certificates remains to be legitimate, supplied the signature was legitimate when utilized.

If the appliance sees a canceled or outdated certificates, however the signature was given earlier than, it’s going to show the signature as genuine because it was beforehand. Most purposes require time stamps; nonetheless, the system clock may be altered.
Takeaway

A timestamp (and LTV) ensures that the signature could also be verified as a result of the signing certificates was legitimate in the mean time of software.
