Hello,

I am able to successfully convert timestamp to datetime using below code:

Timestamp to DateTime:

C#

double dTimeSpan = Convert.ToDouble("1404757800000");
DateTime dtReturn = new DateTime(1970, 1, 1, 0, 0, 0,    DateTimeKind.Utc).AddSeconds(Math.Round(dTimeSpan / 1000d)).ToLocalTime();

Result:

C#

7/8/2014 12:00:00 AM

But i am not able to convert this datetime to correct timestamp. Using below code because it give me wrong timestamp.

Datetime to Timestamp:

C#

DateTime dtEPoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
DateTime dtTime = dtReturn.Subtract(new TimeSpan(dtEPoch.Ticks));
long lngTimeSpan = dtTime.Ticks / 10000;
string strTimeSpan = lngTimeSpan.ToString();

Result:

C#

1404777600000

Please suggest me.

Try this

C#

 date=new Datetime(2014,8,7);
long Timestamp = date.Ticks - new DateTime(1970, 1, 1).Ticks;
    Timestamp /= TimeSpan.TicksPerSecond;
    return Timestamp;

I think this should do the trick.

C#

DateTime dtEPoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
TimeSpan timeSpan = dtReturn - dtEPoch;
string strTimeSpan = timeSpan.ToString();

C#

DateTime oDT = new DateTime(2014, 2, 21);
TimeSpan oTS = new TimeSpan(oDT.Ticks);

Change DateTimeKind.Utc to DateTimeKind.Local then it will work

double dTimeSpan = Convert.ToDouble("1404757800000");
      DateTime dtReturn = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Local).AddSeconds(Math.Round(dTimeSpan / 1000d)).ToLocalTime();

      DateTime dtEPoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Local);
      DateTime dtTime = dtReturn.Subtract(new TimeSpan(dtEPoch.Ticks));
      long lngTimeSpan = dtTime.Ticks / 10000;
      string strTimeSpan = lngTimeSpan.ToString();
