Hi,

How about the following,
type/read the .PEM file with your favorite
editor and look for the certificate header:
then find something along:

-----8<------

Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number: 5 (0x5)
        Signature Algorithm: md5WithRSAEncryption
        Issuer: C=<CountryCode>, ST=<State>, L=<City>, O=<Organisation>,
OU=<Organisational Unit>, CN=<Comment>
        Validity
            Not Before: Aug 20 09:22:57 1999 GMT
            Not After : Aug 18 09:22:57 2004 GMT
        Subject: C=<CountryCode>, ST=<State>, L=<City>, O=<Organisation>,
OU=<Organisational Unit>, CN=<Comment>
        Subject Public Key Info:
            Public Key Algorithm: rsaEncryption
  ----8<----

The validity part says it all..... valid between
20 Aug 1999 -> 18 Aug 2004 at the specified times.

Hope it helped,

Regards,
Nico Baggus
