require 'chilkat'

email = Chilkat::CkEmail.new()

# Load a .eml file into the email object.
success = email.LoadEml("/home/users/chilkat/eml/myEml.eml")

# dtTime is a CkDateTime
dtTime = email.GetDt()
if (email.get_LastMethodSuccess() == false)
    print "Email has no Date header field." + "\n";
    exit
end

# Once we have the CkDateTime object, we can get the date/time in all sorts of formats:

# Get as a RFC822 GMT string:
bLocalTime = false
print dtTime.getAsRfc822(bLocalTime) + "\n";

# Get as an RFC822 string in the local timezone.
# (remember, the daylight savings that existed at the given time in the past is applied)
bLocalTime = true
print dtTime.getAsRfc822(bLocalTime) + "\n";

# Get as a 32-bit UNIX time (local or GMT..)
# The Unix time is number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). 
unixTime = dtTime.GetAsUnixTime(bLocalTime)
print "Unix time: " + unixTime.to_s() + "\n";

# One can also get the as a "DtObj" object for accessing the individual
# parts of the date/time, such as month, day, year, hour, minute, etc.
# The DtObj can be obtained in the GMT or local timezone:
# dtObj is a CkDtObj
dtObj = dtTime.GetDtObj(bLocalTime)
if (dtTime.get_LastMethodSuccess() == false)
    print "This should never really happen!" + "\n";
    exit
end

print dtObj.get_Day().to_s() + "-" + dtObj.get_Month().to_s() + "-" + dtObj.get_Year().to_s() + " " + dtObj.get_Hour().to_s() + 
    ":" + dtObj.get_Minute().to_s() + ":" + dtObj.get_Second().to_s() + "\n";
