Can I get millisecond accuracy in ASP?
VBScript does not support such fine granularity within formatdatetime, datediff, or dateadd.
But there may still be a way to do what you want, depending on your goal.
If you want to count the number of milliseconds between two dates, there are very few scenarios where you could make this work in VBScript. Perhaps if two datetime values are stored in SQL Server, including milliseconds, and you retrieved them using a string... parsing it out and doing all the math yourself (yuck). If that were the case, you could just as easily do the DATEDIFF within SQL Server, and then you wouldn't have to do the math in VBScript. You can do this as follows:
JScript does support a getMilliseconds() method, which gets the milliseconds from the current time:
So it may be possible that you can use Jscript to get millisecond accuracy. Certainly if you define two dates within a script, and you want to know how many milliseconds passed between them, you can do custom math functions which will have to vary calculations depending on how many minutes, seconds etc. have elapsed. But the question is, how valuable is this information?
If you have milliseconds stored in SQL Server, you can get these values to the ASP page simply by adding a DATEPART clause to your query, and returning it as a string. For example:
Of course, once you get that value back to ASP, the greatest utility you will get from it is dumping it to the screen as text.
