// The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
// If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
// establish the cookie as shown at SharePoint Online Authentication

// Indicate that we want a JSON reply

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

// Get as a RFC822 GMT string:
bool bLocalTime = false;
Debug.WriteLine(lastmod.GetAsRfc822(bLocalTime));

// 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;
Debug.WriteLine(lastmod.GetAsRfc822(bLocalTime));

// 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). 
int unixTime = lastmod.GetAsUnixTime(bLocalTime);
Debug.WriteLine("Unix time: " + Convert.ToString(unixTime));

// 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:
Chilkat.DtObj dtObj = lastmod.GetDtObj(bLocalTime);
