如何在Windows中使用python更改系统时区？

Question

How to change system timezone using python's win32api? I've tried using SetTimeZoneInformation.

win32api.SetTimeZoneInformation(year,
                            month,
                            dayofweek,
                            hour,
                            minute,
                            second,
                            milliseconds)

this gives me an error in milliseconds parameter.

TypeError: Objects of type 'int' can not be converted to Unicode.

What is the parameter for SetTimeZoneInformation? Documentation says that it needs privilege for SE_TIME_ZONE_NAME. How to set that in python? Using WMI?

thanks,

Answer 1

Based on Tim Golden's win32api docs , the method takes a tuple of the following form:

[0] int : Bias

[1] string : StandardName

[2] SYSTEMTIME tuple : StandardDate

[3] int : StandardBias

[4] string : DaylightName

[5] SYSTEMTIME tuple : DaylightDate

[6] int : DaylightBias

More to the point, try win32api.GetTimeZoneInformation ( docs ) to see what the tuple ought to look like so that win32api.SetTimeZoneInformation won't complain.

Edit: Getting the necessary privilege

You need the SE_TIME_ZONE_NAME privilege (see here ). There's a handy implementation of changing privileges, AdjustPrivilege over here .

Putting it all together:

import ntsecuritycon, win32security, win32api

def AdjustPrivilege( priv ):
    flags = ntsecuritycon.TOKEN_ADJUST_PRIVILEGES | ntsecuritycon.TOKEN_QUERY
    htoken =  win32security.OpenProcessToken(win32api.GetCurrentProcess(), flags)
    id = win32security.LookupPrivilegeValue(None, priv)
    newPrivileges = [(id, ntsecuritycon.SE_PRIVILEGE_ENABLED)]
    win32security.AdjustTokenPrivileges(htoken, 0, newPrivileges)

# Enable the privilege
AdjustPrivilege(win32security.SE_TIME_ZONE_NAME)

# Set the timezone
win32api.SetTimeZoneInformation((-600,u'Eastern Standard Time',(2000,4,1,3,0,0,0,0),0,u'Eastern Daylight Time',(2000,10,1,2,0,0,0,0),-60))
