Dav*_*dRR 5 vbscript wmi timezone utc timezone-offset
如何使用VBScript确定我的时区偏移量?
Windows操作系统提供TZ环境变量.对于东部标准时间(纽约),其价值为EST5EDT.但是,我正在寻找UTC的有符号整数偏移量.(东部标准时间为-5.)
Dav*_*dRR 10
这是一个修改后的功能,似乎考虑了夏令时.(受到这个SO问题的启发.)
Function GetTimeZoneOffset()
Const sComputer = "."
Dim oWmiService : Set oWmiService = _
GetObject("winmgmts:{impersonationLevel=impersonate}!\\" _
& sComputer & "\root\cimv2")
Set cItems = oWmiService.ExecQuery("SELECT * FROM Win32_ComputerSystem")
For Each oItem In cItems
GetTimeZoneOffset = oItem.CurrentTimeZone / 60
Exit For
Next
End Function

[不考虑夏令时的原始功能.]
这是我对我的问题的答案(原始来源).
对于东部标准时间(纽约),此VBScript函数将返回-5:
Function GetTimeZoneOffset()
Const sComputer = "."
Dim oWmiService : Set oWmiService = _
GetObject("winmgmts:{impersonationLevel=impersonate}!\\" _
& sComputer & "\root\cimv2")
Dim cTimeZone : Set cTimeZone = _
oWmiService.ExecQuery("Select * from Win32_TimeZone")
Dim oTimeZone
For Each oTimeZone in cTimeZone
GetTimeZoneOffset = oTimeZone.Bias / 60
Exit For
Next
End Function
