Need VBS version of Excel date conversion

Last Modified: 2016-08-31
I have this in Excel but need a vbscript version to run on CMD line, i.e. cscript dateconvert.vbs 1255635089


I have this so far...

BTW, I'm not an expert VBS coder as you can see. So, I'm open to better / cleaner solution.

Set objArgs = WScript.Arguments
nEpochVal = objArgs(0)
Dim dblVbEpoch
    dblVbEpoch = CDbl(DateAdd("s", nEpochVal, #1970/1/1#))

sTime=FormatDateTime(DateAdd("n", CurrentTZOffset(), CDate(dblVbEpoch)),3)
sTime=Replace(sTime," ","")
WScript.Echo myDateFormat(DateAdd("n", CurrentTZOffset(), CDate(dblVbEpoch))) & " " & sTime

Function CurrentTZOffset()
    With CreateObject("WScript.Shell") 
        CurrentTZOffset = - .RegRead( _ 
    End With
End Function

Function myDateFormat(myDate)
    d = WhatEver(Day(myDate))
    m = WhatEver(Month(myDate))    
    y = Year(myDate)
    myDateFormat= y & "_" & m & "_" & d
End Function

Function WhatEver(num)
    If(Len(num)=1) Then
    End If
End Function

Open in new window

But, running cscript /nologo EpochToDate.vbs 1255635089
... echos it as: 2009_10_15 9_31_29AM
... which is fine except:

- I don't want the AM or PM suffix
- If the hour is a single digit, I'd like it prefixed with a zero. This, for sorting reasons.
