import { CkDateTime, DtObj, Email } from '@chilkat/react-native'

function chilkatExample() {
  const email = new Email();

  // Load a .eml file into the email object.
  email.loadEml('/home/users/chilkat/eml/myEml.eml');

  const dtTime = new CkDateTime();
  dtTime.setFromRfc822(email.emailDateStr);

  // Once we have the CkDateTime object, we can get the date/time in many different formats:

  // Get as a RFC822 GMT string:
  let bLocalTime = false;
  console.log(dtTime.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;
  console.log(dtTime.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). 
  const unixTime = dtTime.getAsUnixTime(bLocalTime);
  console.log(`Unix time: ${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:
  const dtObj = new DtObj();
  dtTime.toDtObj(bLocalTime, dtObj);

  if (!dtTime.lastMethodSuccess) {
    console.log('This should never really happen!');
    return;
  }

  console.log(`${dtObj.day}-${dtObj.month}-${dtObj.year} ${dtObj.hour}:${dtObj.minute}:${dtObj.second}`);
