Figure 10.3: Transaction deadline not met

When we meet the deadline, it looks like this:

Figure 10.4: Transaction deadline met

Let's dissect our example. First, we define a deadline for the transaction with the time.Duration() variable. In my experience, the Millisecond resolution is optimal; however, it does take some time to get used to calculating it. Feel free to use whichever resolution you prefer. We mark the beginning with the Start variable, do some calculations, and mark the completion with the End variable. The magic happens after this. We would like to calculate the difference between the deadline and the transaction duration, but we cannot do it directly. We need to convert the Duration value to Transaction time. This is done the same way when we created our deadline. We simply use the Nanosecond resolution, which is the lowest resolution we should go to. However, in this case, you can use the resolution you would like. After conversion, we can easily compare and decide whether the transaction is fine or not.

Now, let's see how we can manipulate time.
