I have a string in the form "yyyy-mm-dd hh:mm:ss.mmm" (where the end is milliseconds)

I'd like to convert it to a number, preferably a Date, which preserves all the information

I've tried CDate(), eg.

Dim dateValue As Date
dateValue = CDate("2017-12-23 10:29:15.223")

But get a type mismatch error

A Date type holds the number of days since December 30 1899 with a precision of one second. Though it's still possible to hold the milliseconds by storing the date in a currency type since it can hold 4 extra digits compared to a Date/Double.

So an alternative would be to store the date as a timestamp in a Currency type representing the number of seconds since December 30 1899:

Public Function CDateEx(text As String) As Currency
    Dim parts() As String
    parts = Split(text, ".")
    CDateEx = CCur(CDate(parts(0)) * 86400) + CCur(parts(1) / 1000)
End Function

And to convert the timestamp back to a string:

Public Function FormatDateEx(dt As Currency) As String
    FormatDateEx = Format(dt / 86400, "yyyy-mm-dd HH:mm:ss") & "." & ((dt - Fix(dt)) * 1000)
End Function

Why not use DateAdd to add the last 0.233 seconds after obtaining the whole second as a date Value?

Dim Str As String, MS As String
Dim DateValue As Date
Dim L as Integer
Str = "2017-12-23 10:29:15.223"
For L = 1 to Len(Str)
    If Left(Right(Str, L), 1) = "." Then
        MS = "0" & Right(Str, L)
        Str = Left(Str, Len(Str) - L)
        Exit For
    End If
Next L
DateValue = CDate(Str)
If MS <> "" Then DateValue = DateAdd("S",MS,DateValue)

How to: Display Milliseconds in Date and Time Values, In this article, learn how to include a date and time's millisecond component in formatted date and time strings in .NET. This example uses the TimeValue function to convert a string to a time. You can also use date literals to directly assign a time to a Variant or Date variable, for example, MyTime = #4:35:17 PM#. Dim MyTime MyTime = TimeValue("4:35:17 PM") ' Return a time. See also. Functions (Visual Basic for Applications) Support and feedback

The code below contains all the components you might need to manage your dates and their milliseconds.

Private Sub ParseTime()

    Dim strTime As String
    Dim Sp() As String
    Dim Dt As Double

    strTime = "2017-12-23 10:29:15.221"
    Sp = Split(strTime, ".")
    strTime = Sp(0)

    Dt = CDbl(CDate(strTime))
    strTime = "yyyy-mm-dd hh:mm:ss"
    If UBound(Sp) Then
        Dt = Dt + CDbl(Sp(1)) * 1 / 24 / 60 / 60 / (10 ^ Len(Sp(1)))
        strTime = strTime & "." & CInt(Sp(1))
    End If
    Debug.Print Format(Dt, strTime)
End Sub

I can't say that I am entirely happy with the solution because the print is only implicitly equal to the date value. However, I found that the formerly valid Date/Time format, like "yyyy-mm-dd hh:mm:ss.000", doesn't seem to work since 2007. However, it should be possible to prove conclusively that the Date/Time value is equal to its rendering by the format mask I includedcd above.

how to get Now() formated with millisecond ? - MSDN, The VBA function Now doesn't return milliseconds. You can use the Dim s As String Google: Can I get VBA equivalent of DateTime.Now. VBA CDate ()function is one of the most commonly used date functions to convert a date stored in a “String” variable into a date data type. The example given below will help make the concept clear. Open your MS Excel and enter the date in cell A1 in the following format: March 24, 2014

Michael's answer has an error (as spotted by Jim) when the decimal part rounds up.

The following corrects the error (slightly modified for tenths of seconds rather than milliseconds and with a parameterized format pattern).

Public Function FormatDateEx(dt As Currency, formatPattern As String) As String
    Rem FormatDateEx = Format(dt / 86400, "yyyy-mm-dd HH:mm:ss") & "." & ((dt - Fix(dt)) * 1000)
    Dim decimalPart As Double
    decimalPart = Round(((dt - Fix(dt)) * 10), 0)
    If (decimalPart = 10) Then
        FormatDateEx = format(dt / 86400, formatPattern) & ".0"
        FormatDateEx = format(Fix(dt) / 86400, formatPattern) & "." & decimalPart
    End If
End Function

How do I make the Now function display miliseconds in VBA macro , See: VBA Tips & Tricks: Excel VBA TimeStamp – Milliseconds using Excel VBA to the Function provided in the link I sent you to remove the date piece. Strings. Right(Strings.Format(Timer, "#0.00"), 2) End Function. This total number of milliseconds is the elapsed milliseconds since timestamp or unix epoch counting from 1 January 1970. Just enter the milliseconds value and press the Convert to Date button to find the date. You can also set the milliseconds value from Now button to the current timestamp milliseconds. For example 1471300214792 milliseconds is converted to date as 16 August 2016 01:30:14.

Use the Left$ function to trim the decimal point and milliseconds:

Dim dateValue As Date
dateValue = CDate(Left$("2017-12-23 10:29:15.223", 19))

Excel time in milliseconds, Miliseconds: (Now-Date)*24*60*60*1000 it wouldn't be at all accurate; the system clock used by Now() does not have millisecond accuracy. Convert string date to date format. CDate part of the formula converts the string to a date. Format part of the formula lets you decide what format the date should be in. datestr = Format (CDate (Cells (1, 1).Value), "dd/mm/yyyy") datestr2 = Format (CDate (Range ("A1").Value), "dd/mm/yyyy") datestr3 = Format (CDate ("2018-01-10"), "dd/mm/yyyy")

Convert Timestamp 00:00:00.000 into total seconds AND milliseconds, If it is formatted as a date, it's even simpler: It is looking at the cell A1 as a text string, then converts parts of it to numbers, then adds them together appropriately � Select a cell which you will place the date in, type this formula = (G2/86400000)+DATE (1990,1,1), G2 is the milliseconds cell, 1990,1,1 is the start date, press Enter key and drag autofill handle down to the cells for getting a list of decimal number. See screenshot:

How to quickly convert milliseconds to a date in Excel?, Have you ever tried to calculate a date by a given number of milliseconds? For instance, 112233445566 is the number of milliseconds that far from a specific date,�

  • Possible duplicate of VB6 Date data type: precision and formatting
  • Possible duplicate of Microsecond support for VT_DATE type
  • This is a great solution, thanks Michael. Although I think there is a minor bug in FormatDateEx. I believe you need FormatDateEx = Format( *Fix*(dt) /86400, ..... Try testing with FormatDateEx(CDateEx("15:59:58.921")). Without the fix the seconds become 59, not 58 (In Excel 2016 64 bit windows). I have not thoroughly tested this so be careful.
  • Unfortunately, as other answers have highlighted, it is the Date datatype that's the problem; it does not hold numbers to ms precision. So DateAdd has no effect, as the decimal portion of the date is cut off. You can test this with a debug.print DateValue before and after the DateAdd
