OK I figured out the first one. It is not the number of naonoseconds. It
is 100 nanosecond intervals. So that makes sense as for the 100 days
when it should be one day.

Still working on the second one.

 

 

Hello and Merry Christmas,

 

I am feeling pretty dumb here and would like to wrap up one of my
projects before the holiday.

 

Currently I am trying to do some calculations using w32tm.exe to
validate my math...and my math appears to be wrong.

For example I Google how many nanoseconds in a day. From multiple
sources I get 86,400,000,000,000. Fine then w32tm.exe should match
saying 1 day....but it doesn't  It says 100 days????

 

C:\Users\jbonner>w32tm.exe /ntte 86400000000000

100 00:00:00.0000000 - 4/10/1601 5:00:00 PM

 

A day is a day regardless so I can't see that time zone would matter for
this simple calculation??

 

So let's say Google is wrong and I use 864,000,000,000 which does show
as one day. 

 

C:\Users\jbonner>w32tm.exe /ntte 864000000000

1 00:00:00.0000000 - 4/10/1601 5:00:00 PM

 

Fine w32tm.exe has an epoch of 1-1-1601. I want the number of
nanoseconds till 1-1-1901. That would be

 

300 (1901-1601)

365 (days in a year)

300 * 365 = 109,500 days

 

109500 days * 864000000000 (nanoseconds in a day) =
94,608,000,000,000,000

 

Close but no dice.

 

C:\Users\jbonner>w32tm.exe /ntte 94608000000000000

109500 00:00:00.0000000 - 10/20/1900 5:00:00 PM

 

So I am pretty confused and any clarification would be greatly
appreciated.

JB
