I think you're looking for something that doesn't exist, unless the
windows epoch handling is non-posix. In the Unix/posix environment, the
epoch is always UTC and the conversion to local time-zone value occurs as
part of the time formatting - there's no such animal as 'local epoch'. I'd
look at the system returning these values and make sure the time zone is
set correctlyraw, Robert P [mailto:user-33cf07af04dd@xymon.invalid]

A little more digging and I see

Subject: BBWin V.12 filesystem epoch time and local time conflict
I have the [file:] set up in central mode on our BBWin V.12 client and
it
returns the following client data to the Hobbit server.
[file:c:\Alligate\AAATEST]
type:0x00020 (file)
mode:777 (not implemented)
linkcount:1
owner:0 (not implemented)
group:0 (not implemented)
size:0
atime:1214222069 (2008/06/23-11:54:29)
ctime:1213796626 (2008/06/18-13:43:46)
mtime:1214222069 (2008/06/23-11:54:29)
On my hobbit server hobbit-clients.cfg I have
FILE c:\Alligate\AAATEST red MTIME<88200
The YYYY/MM/DD-HH:MM:SS atime, ctime and mtime are local time.
During testing I noticed that the red icon would come on before I had
expected.
I decided to do a little checking and using a web epoch time calculator.
If I enter 2008/06/23-11:54:29 it returns the epoch time of 1214236469,
which
does not match mtime epoch time above.
If I enter the epoch mtime 1214222069 I get Mon Jun 23 2008 07:54:29
GMT-0400 (EDT) which does not match the date.
If I enter epoch time 1214236469 I get Mon Jun 23 2008 11:54:29 GMT-0400
(EDT)
It seems that the YYYY/MM/DD-HH:MM:SS time is reported in local time and
the
epoch time is reported in GMT time which throws things off by four
hours.
The following is the code in filesystem
325 reportData << format("type:0x%05x ") %
handle_file_info.dwFileAttributes;
326 if (handle_file_info.dwFileAttributes &
FILE_ATTRIBUTE_DIRECTORY)
327 reportData << "(dir)" << endl;
328 else
329 reportData << "(file)" << endl;
330 reportData << "mode:777 (not implemented)" << endl;
331 reportData << format("linkcount:%u") %
handle_file_info.nNumberOfLinks
<< endl;
332 reportData << "owner:0 (not implemented)" << endl;
333 reportData << "group:0 (not implemented)" << endl;
334 reportData << format("size:%lu") % fsize << endl;
335 string output;
336 GetTimeString(handle_file_info.ftLastAccessTime, output);
337 reportData << "atime:" << output << endl;
338 GetTimeString(handle_file_info.ftCreationTime, output);
339 reportData << "ctime:" << output << endl;
340 GetTimeString(handle_file_info.ftLastWriteTime, output);
341 reportData << "mtime:" << output << endl;
342 fclose(f);
343 return true;
GetTimeString is a function in the filesystem code which follows.
bool AgentFileSystem::GetTimeString(const FILETIME & filetime,
string & output) {
255 __int64 ftime = (filetime.dwHighDateTime * MAXDWORD) +
filetime.dwLowDateTime;
256 SYSTEMTIME fsystime;
257 FILETIME floctime;
258 time_t epoch;
259
260 if (::FileTimeToLocalFileTime(&filetime, &floctime) == 0) {
261 return false;
262 }
263 if (::FileTimeToSystemTime(&floctime, &fsystime) == 0) {
264 return false;
265 }
266 utils::SystemTimeToTime_t(&fsystime, &epoch);
267 stringstream reportData;
268 reportData << format("%llu (%02d/%02d/%d-%02d:%02d:%02d)")
269 % (unsigned __int64)epoch
270 % fsystime.wYear
271 % fsystime.wMonth
272 % fsystime.wDay
273 % fsystime.wHour
274 % fsystime.wMinute
275 % fsystime.wSecond;
276 output = reportData.str();
277 return true;
278 }
It seems to me that after line 266 there needs to be a couple lines that
converts the GMT epoch to local epoch.
The function GetTimeString seems to be the code that is returning the
time
information. I have not been able to find this code in the BBWin svn so
I
am
not sure if this is a local function or a system function.
I am not a Window type guy and no very little about such things. Can a
super
duper window type person peruse this and see what they can find.
Tanks
Thanks
