I would like to get valid timestamp in my application so I wrote:
public static String GetTimestamp(DateTime value)
{
return value.ToString("yyyyMMddHHmmssffff");
}
// ...later on in the code
String timeStamp = GetTimestamp(new DateTime());
Console.WriteLine(timeStamp);
output:
000101010000000000
I wanted something like:
20140112180244
What have I done wrong?
var Timestamp = new DateTimeOffset(DateTime.UtcNow).ToUnixTimeSeconds();
internal static string UnixToDate(int Timestamp, string ConvertFormat)
{
DateTime ConvertedUnixTime = DateTimeOffset.FromUnixTimeSeconds(Timestamp).DateTime;
return ConvertedUnixTime.ToString(ConvertFormat);
}
int Timestamp = (int)DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds;
Usage:
UnixToDate(1607013172, "HH:mm:ss"); // Output 16:32:52
Timestamp; // Output 1607013172
Int32 unixTimestamp = (Int32)(TIME.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;
"TIME" is the DateTime object that you would like to get the unix timestamp for.
var timestamp = DateTime.Now.ToFileTime();
//output: 132260149842749745
This is an alternative way to individuate distinct transactions. It's not unix time, but windows filetime.
From the docs:
A Windows file time is a 64-bit value that represents the number of 100-
nanosecond intervals that have elapsed since 12:00 midnight, January 1, 1601
A.D. (C.E.) Coordinated Universal Time (UTC).
For UTC:
string unixTimestamp = Convert.ToString((int)DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);
For local system:
string unixTimestamp = Convert.ToString((int)DateTime.Now.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);
