Windows SetLocalTime

[Podi]

I am trying to set the system time on my Windows computer, but avoid
using the DOS command (date, time).

Does anyone know what parameter to pass to function SetLocalTime?

Thanks a bunch,

Google will usually find the documentation of anything in the
Windows API however sometimes it also helps to add "msdn" to
your search as in:

<url:http://www.google.com/search?client=....mozilla%3Aen-
US%3Aofficial_s &hl=en&q=setloc altime+msdn&btn G=Google+Search >

Adding site:msdn.micro soft.com is even better (but alas more typing):

<url:http://www.google.com/search?hl=en&lr=&client=firefox-
a&rls=org.mozil la%3Aen-US%3Aofficial_s &q=setlocaltime +site%
3Amsdn.microsof t.com&btnG=Sear ch>

Re: Windows SetLocalTime

Yes, thank you.

I found the function SetLocalTime or SetSystemTime to set the time from
MSDN http://msdn2.microsoft.com/en-us/library/ms724942.aspx. I am
having trouble passing parameter to the functions in Python.

Ok I see, you will probably need these 2 bits of the ctypes
documentation:

http://docs.python.org/lib/ctypes-structures-unions.html

http://docs.python.org/lib/ctypes-pointers.html

From there on geting to this is farly straight forward:

from ctypes import *
from ctypes.wintypes import WORD

class SYSTEMTIME(Stru cture):
_fields_ = [
( 'wYear', WORD ),
( 'wMonth', WORD ),
( 'wDayOfWeek', WORD ),
( 'wDay', WORD ),
( 'wHour', WORD ),
( 'wMinute', WORD ),
( 'wSecond', WORD ),
( 'wMilliseconds' , WORD ),
]

GetSystemTime = windll.kernel32 .GetSystemTime

st = SYSTEMTIME()

GetSystemTime( pointer( st ) )

print st.wYear, st.wMonth, st.wDayOfWeek

A bit more digging into the docs will get to this:

prototype = WINFUNCTYPE( None, POINTER( SYSTEMTIME ) )
paramflags = (1, "lpSystemTi me" ),
GetSystemTime = prototype(("Get SystemTime", windll.kernel32 ), paramflags )

st = SYSTEMTIME()
GetSystemTime( st )
print st.wYear, st.wMonth, st.wDayOfWeek

Which will give a much better error message if you try to
pass something other than a SYSTEMTIME, as well as wrapping
the argument in pointer for you.
