Verify a timestamp certificate

Note: as always with computers, the "garbage-in-garbage-out" principle applies: the quality of the output depends on the quality of the input. If you want to be absolutely certain that your certificate is correct, you must ensure the following:

• You or some other trustworthy expert has investigated this program and verified that it rejects all incorrect certificates.
• The person / organization who installed this program is trustworthy. In other words, you must be sure that you are actually using the version of the program that was verified by you or your expert.
• The source of block chain information is trustworthy.
