Using stopwatch and it doesn't work properly

Question

I'm using discord bot, and I'm trying to check the time of the time service but its only shows the time only once and then writes 0

public async Task HandleCommand(SocketMessage messageParam)
{
    // Don't process the command if it was a System Message
    var message = messageParam as SocketUserMessage;

    if (message == null || message.Author.IsBot) 
       return;

    Console.WriteLine(message.Author);
    time.Start();

    // Create a number to track where the prefix ends and the command begins
    int argPos = 0;

    // Determine if the message is a command, based on if it starts with '!' or a mention prefix
    if (!(message.HasCharPrefix('>', ref argPos))) 
        return;

    // Create a Command Context
    var context = new CommandContext(dbot, message);
    Last = message.Author;

    // Execute the command. (result does not indicate a return value, 
    // rather an object stating if the command executed successfully)
    var result = await commands.ExecuteAsync(context, argPos, services);

    time.Stop();
    time.Reset();
}

and it calls this function

[Command("ping"), Summary("Echos a message.")]
public async Task Say()
{
    // ReplyAsync is a method on ModuleBase
    await ReplyAsync("PONG " + CommandHandler.time.ElapsedMilliseconds);
}

尝试在异步函数中创建计时器。
