我也是刚学来的,看看对你有没有帮助:

Option Explicit
Private Declare Function NetRemoteTOD Lib "Netapi32.dll" ( _
tServer As Any, pBuffer As Long) As Long

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 Type TIME_ZONE_INFORMATION
Bias As Long
StandardName(32) As Integer
StandardDate As SYSTEMTIME
StandardBias As Long
DaylightName(32) As Integer
DaylightDate As SYSTEMTIME
DaylightBias As Long
End Type

Private Declare Function GetTimeZoneInformation Lib "kernel32" (lpTimeZoneInformation As TIME_ZONE_INFORMATION) As Long
Private Declare Function NetApiBufferFree Lib "Netapi32.dll" (ByVal lpBuffer As Long) As Long

Private Type TIME_OF_DAY_INFO
tod_elapsedt As Long
tod_msecs As Long
tod_hours As Long
tod_mins As Long
tod_secs As Long
tod_hunds As Long
tod_timezone As Long
tod_tinterval As Long
tod_day As Long
tod_month As Long
tod_year As Long
tod_weekday As Long
End Type

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As Any, Source As Any, ByVal Length As Long)

Public Function getRemoteTOD(ByVal strServer As String) As Date
Dim result As Date
Dim lRet As Long
Dim tod As TIME_OF_DAY_INFO
Dim lpbuff As Long
Dim tServer() As Byte
tServer = strServer & vbNullChar
lRet = NetRemoteTOD(tServer(0), lpbuff)

If lRet = 0 Then
CopyMemory tod, ByVal lpbuff, Len(tod)
NetApiBufferFree lpbuff
result = DateSerial(tod.tod_year, tod.tod_month, tod.tod_day) + _
TimeSerial(tod.tod_hours, tod.tod_mins - tod.tod_timezone, tod.tod_secs)
getRemoteTOD = result
Else
Err.Raise Number:=vbObjectError, Description:="不能取到服务器时间 !"
End If
End Function

'要运行该程序,通过如下方式调用。
Private Sub Command1_Click()
Dim d As Date
d = getRemoteTOD("\\服务器IP")
MsgBox d
End Sub
