Using SetSystemTime

[Joey_k29]

How would I design an operation that stores the current time to the millisecond, then changes the current time to some other time accurate to a millisecond, and then when it is done, restores the time when the operation started(i.e the storage of the currrent time). Thank you for your help.
Sincerely,
Joseph

To get the current time in milliseconds try

Private Declare Sub GetSystemTime Lib "kernel32" (lpSystemTime As SYSTEMTIME)
 
Private Type SYSTEMTIME
    wYear As Integer
    wMonth As Integer
    wDayOfWeek As Integer
    wDay As Integer
    wHour As Integer
    wMinute As Integer
    wSecond As Integer
    wMilliseconds As Integer
End Type
 
Private Function TimeToMillisecond() As String
    
    Dim DaAnswer As String
    Dim MyMillTime As SYSTEMTIME
    
    On Error Resume Next
    GetSystemTime MyMillTime
    DaAnswer = Hour(Now) & ":" & Minute(Now) & ":" & Second(Now) & ":" & MyMillTime.wMilliseconds
    TimeToMillisecond = DaAnswer
    
End Function

I'm a little confused after this however. ??You want to get the current time in milliseconds, convert it to "something else" and then convert is back??

I want to get the current time(store it in currenttime). Then, I want to set the time to some predefined time(set the time to newtime). Then after I execute some code I want to set the time back to currenttime(the value stored earlier). Thanks for the help
