GetTimeZoneInformation question

Hi all,

The following code snippet isn't working terribly well for
me. I can get 
the Bias, StandardName and DaylightName, but everything else
is goofed 
up. The alignment seems ok, but maybe I've missed something
or maybe I 
have to do extra work to unpack the SYSTEMTIME structures.

require 'windows/time'
include Windows::Time

buf = 0.chr * 172 # sizeof(TIME_ZONE_INFORMATION)
GetTimeZoneInformation(buf)

p buf[0,4].unpack('L')[0]    # Bias
p buf[4,64].tr("",'')      # StandardName
p buf[68,2].unpack('S')[0]   # Year
p buf[70,2].unpack('S')[0]   # Month
p buf[72,2].unpack('S')[0]   # DOW
p buf[74,2].unpack('S')[0]   # Day
p buf[76,2].unpack('S')[0]   # Hour
p buf[78,2].unpack('S')[0]   # Minute
p buf[80,2].unpack('S')[0]   # Second
p buf[82,2].unpack('S')[0]   # Millisecond
p buf[84,4].unpack('S')[0]   # StandardBias
p buf[88,64].tr("",'')     # DaylightName
p buf[152,2].unpack('S')[0]  # Year
p buf[154,2].unpack('S')[0]  # Month
p buf[156,2].unpack('S')[0]  # DOW
p buf[158,2].unpack('S')[0]  # Day
p buf[160,2].unpack('S')[0]  # Hour
p buf[162,2].unpack('S')[0]  # Minute
p buf[164,2].unpack('S')[0]  # Second
p buf[166,2].unpack('S')[0]  # Millisecond
p buf[168,4].unpack('L')[0]  # DaylightBias

Regards,

Dan

Oh, silly me. Disregard.
