Thread locking and ASP.NET [modified]

[binarymax]

Hi, I have some short questions about locking threads in ASP.NET. Normally I use C# console/winforms but in this case I need to write it in VB for ASP.NET. My questions are there any drawbacks to this code in a high-volume of requests? Is this completely wrong for an ASP.NET application? If so what do you recommend? The purpose here is to lock a timestamp and be sure it is set uniquely throughout all the sessions on the web server:

Protected Shared TimeStamp As Date
Protected Shared Sub SetUniqueTimeStamp()

    Try
        ' Request the lock, and block until it is obtained.
        Monitor.Enter(TimeStamp)
        ' When the lock is obtained, set the Timestamp.
        TimeStamp = Now
    Finally
        'Guarantee at least 1ms tick for uniqueness
        Thread.Sleep(1)
        ' Ensure that the lock is released.
        Monitor.Exit(TimeStamp)
    End Try

End Sub

This is just an example based on some code I altered from this at MSDN: Monitor.Enter Method[^] Many thanks in advance!
