其实用自带的formatdatetime也差不多了，瞧瞧下面这个定义的东东吧。

' 格式化时间(显示)
' 参数：n_Flag
' 1:"yyyy-mm-dd hh:mm:ss"
' 2:"yyyy-mm-dd"
' 3:"hh:mm:ss"
' 4:"yyyy年mm月dd日"
' 5:"yyyymmdd"
' 6:"yyyymmddhhmmss"
' ============================================
Function FormatTime(s_Time, n_Flag)
 Dim y, m, d, h, mi, s
 FormatTime = ""
 If IsDate(s_Time) = False Then Exit Function
 y = cstr(year(s_Time))
 m = cstr(month(s_Time))
 If len(m) = 1 Then m = "0" & m
 d = cstr(day(s_Time))
 If len(d) = 1 Then d = "0" & d
 h = cstr(hour(s_Time))
 If len(h) = 1 Then h = "0" & h
 mi = cstr(minute(s_Time))
 If len(mi) = 1 Then mi = "0" & mi
 s = cstr(second(s_Time))
 If len(s) = 1 Then s = "0" & s
 Select Case n_Flag
 Case 1
 ' yyyy-mm-dd hh:mm:ss
 FormatTime = y & "-" & m & "-" & d & " " & h & ":" & mi & ":" & s
 Case 2
 ' yyyy-mm-dd
 FormatTime = y & "-" & m & "-" & d
 Case 3
 ' hh:mm:ss
 FormatTime = h & ":" & mi & ":" & s
 Case 4
 ' yyyy年mm月dd日
 FormatTime = y & "年" & m & "月" & d & "日"
 Case 5
 ' yyyymmdd
 FormatTime = y & m & d
 case 6
 'yyyymmddhhmmss
 FormatTime= y & m & d & h & mi & s
 End Select
End Function

呵呵，会不会很罗嗦？
