cert = chilkat.CkCert()

# Get the certificate valid-from date/time
# ckdt is a CkDateTime
ckdt = cert.GetValidFromDt()
# Get the local timestamp string.
print("Valid from: " + ckdt.getAsTimestamp(True))
# Valid from: 2017-03-17T19:00:00-05:00

# Now get the date/time as another object where we can get the individual numeric date parts.
# dt is a CkDtObj
dt = ckdt.GetDtObj(True)
print(str(dt.get_Day()) + "/" + str(dt.get_Month()) + "/" + str(dt.get_Year()) + "  " + str(dt.get_Hour())\
     + ":" + str(dt.get_Minute()))

# Get the certificate valid-to date/time
# ckdt is a CkDateTime
ckdt = cert.GetValidToDt()
print("Valid to: " + ckdt.getAsTimestamp(True))
# Valid to: 2020-03-18T18:59:59-05:00
# dt is a CkDtObj
dt = ckdt.GetDtObj(True)
print(str(dt.get_Day()) + "/" + str(dt.get_Month()) + "/" + str(dt.get_Year()) + "  " + str(dt.get_Hour())\
