How to time events?

[pstrusi]

Hi NT,

I'd like simply to calculate the time ( in secs ) between two events, but I'm not sure about which is the best, simple and reliable method.

I've seen the typical example:
DateTime.Now.Ticks - Time[0].Ticks

Can I do the same but getting the seconds of difference? I'm not used to manage Time in C#, so I don't know what a tick means in time.

Any help would be great


Thanks in advance

Hello,

Thank you for the question.

One way of doing this would be using DateTime.Subtract, here is a simple example that checks the amount of seconds between 1 bar ago and the Current computer time:

if(Historical) return;
DateTime timeA = DateTime.Now;
DateTime timeB = Time[1];

int seconds = timeA.Subtract(timeB).Seconds;
Print(seconds);

Here is more information on DateTime and TimeSpan, TimeSpan is the object Subtract returns.

I look forward to being of further assistance.

2 questions:

- That difference in seconds would it be an integer value, right ? or would it be a Time structure data?

- Let's suppose that we have a difference > 60 secs, your procedure would give a value > 60 or other form?

Hello,

For a total time in seconds greater than 60 seconds, you could use the TotalSeconds property, for a complete list of options, please refer to the MSDN documentation on TimeSpan.

here is a simple test you can do on your end to see that this produces 180 seconds for 3 minutes of a TimeSpan:

TimeSpan span = new TimeSpan(0, 3, 0);
Print(span.TotalSeconds);

The Property would be an int type, the span would be your TimeSpan object.

I look forward to being of further assistance.
