# 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) + "\n";
# 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 dt.get_Day().to_s() + "/" + dt.get_Month().to_s() + "/" + dt.get_Year().to_s() + "  " + dt.get_Hour().to_s() + 
    ":" + dt.get_Minute().to_s() + "\n";

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