How to convert it to DateTime time.

Most of the current strategies are to convert to string, and then

DateTime dateTimeStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1));

long lTime = long.Parse(timeStamp + < span style="color: #800000;">"0000000" );

TimeSpan toNow = new TimeSpan(lTime);

dateTimeStart.Add(toNow);

I tried it, and in Parse, it prompts that int64 is too large or too small.

Implement

 DateTime dtStart2 = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime (timeStamp));

Effects

DateTime dateTimeStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1));

long lTime = long.Parse(timeStamp + < span style="color: #800000;">"0000000" );

TimeSpan toNow = new TimeSpan(lTime);

dateTimeStart.Add(toNow);

 DateTime dtStart2 = TimeZone.CurrentTimeZone.ToLocalTime( new DateTime(timeStamp));
