Inserting Date/Time into MS Access Database
I'm trying to insert a timestamp into an MS Access Database using the
Labview database connectivity toolset. However, I keep getting an
error saying that the parameter is in the incorrect format. I'm
using the "DB Tools Format DateTime String.vi", and it doesn't seem to
I don't have the answer to your question, but....
How did you get information to be written into MS Access from labview.
If you are using this function to create the date but using SQL to put the date into the DB, this is probably the cause of your problem, because the VI adds a header to your string which is removed later by the parser. If you want to use this date in an SQL command, you should build it yourself or remove the header.
As for roboticstudent, just look at the examples in the example finder to see how to interact with databases.
I tried it both ways. I tried using the format date/time into
string where it would return "11/7/05 8:22:34 PM", which I then tried
to insert in to the DB, but to no avail. I even tried various
formats, changing the order of the numbers, etc., but it doesn't seem
It would be easiest if you post your code, or at least an image of it.
Also, which error exactly are you getting? Is it possible you're trying to enter a string into a numeric field (for example)? If I define a date\time field in Access and then use Insert Data (with the LV format...Inserting Date/Time into MS Access Database #2

Do you have /excl in the command line to open the database.
Is the second user getting an error message? You might want to be a
little more verbose in your problem description...like error messages,
method of opening the file, and the like.

Check the users rights, they must have the right to create and delete files
in the database folder.

I have a situation in a Korn shell script in which I have to add a time

also in the form "hhmm", both being in 24-hour format. Both variables
have already been validated to ensure that they are formatted
correctly. Is there any comand/script which will add these 2 together
to get a new time-of-day?
For example, I have a time-of-day variable containing "1430" (2:30 PM),
and a time period variable containing "340" (3 hours and 40 minutes).
I want to add them together to get "1810&q..."You don't have exclusive access to your database at this time" (Access 2003)

The only thing she did today, according to her, was to download and

She has rebooted and there are no other versions of Access running.
The shortcut that launches the application does point to a version of
Access (2003) because the installation wizard found an existing
version on her PC. I believe it points to Office 11.
Nevermind. She uninstalled the Avery Label Wizard and the problem

I'm guessing there is an easy way to do this but I keep going around
in circles in the documentation.
I have a time stamp that looks like this (corresponding to UTC time):
start_time = '2007-03-13T15:00:00Z'
I want to convert it to my local time.
start_time = time.mktime(time.strptime(start_time, '%Y-%m-%dT%H:%M:
start_time -= time.timezone
This was working fine now, but if I do it for a date next week (such
as March 13th in the above example), it breaks because my local time
moves to daylight savings time this weekend. So my time is now off by

I would like to compare the speed of two algorithms
solving the same problem.
As far as I understood, the tic-toc command gives
the time difference between the beginning and the
end of the computation, without taking into account
the time spent by the processor doing something else.
I'm using a multi-processor multi-users machine and
the CPU time used by my process is not 100% and
is not constant. The measured speeds are fluctuating
so much that I can hardly conclude anything.
Is it possible to obtain realistic measurements of
the speed of my algorithms?

Yes, time/time is an integer. If you need more precision than integer than you can do something like this as an example...

That's essentially what I did. Thanks for the confirmation.
My concern is that time has the potential of being much larger than an
integer can hold, but then it would have a lot more precision than a
real can hold either. I guess it is best to do time math in the time
domain until you need to convert it to something else, like a trig
function, e.g. sin(pi*1e-9*real((2*freq*no...Times Returned by TIME()
I would have posted this on the Quicksilver group but couldn't find it.
We have a Quicksilver system that picks up files from a Windows eftpos
application. There have been some slowdowns in the process and we've
added some logging to identify the culprit. When the QS app detects a
file, it writes a log record using time derived from TIME(). It shells
out to a Clipper app which returns ADIR() data on the file. What we are
finding on the test PC (XP) is that the ADIR() time of the file is
approximately 2 seconds later than the TIME() value recorded.
Does anyone have an explanation?
Th...Re: Access to UTC time with servers running in local time
There is an undocumented way of getting the server's utc time in seconds
just like the time() system call on the server would return it:
select dbinfo( 'utc_current') from systables where tabid = 99
(There also is a dbinfo('utc_to_datetime', <some_utc_int>) to convert it
to a string. But unfortunately it uses local time).
If you want it in ascii and are willing to use esqlc, you could do this:
struct tm *tm;
exec sql begin declare section;
exec sql end declare section;
exec sql whenever error stop;
exec sql database sysmaster;
exec sql select dbinfo( 'utc_current') into :tim
from systables where tabid = 99;
printf("utc time %d\n", tim);
tm = gmtime((time_t *)&tim);

I am building a user login vi with Labview 8.2 that checks whether stored date/time values in the user record (MS SQL Server Express) have expired. I retrieve data/time values from the database as variants and use the database variant to data vi wired to a string data type, getting a mm/dd/yyyy hh:mm:ss AM/PM output string. I can convert this to a numeric date/time for comparison to the current date/time by parsing the string and using the cluster to numeric date/time vi. In testing of this, sometimes I get off by an hour, due to DST confusion I suppose. This is not a killer issue. However, I am concerned about how this will work in other countries, where the variant to data conversion on a date/time value should sometines yield a dd/mm/yyyy etc. string perhaps (?)
Is there a simpler, and internationally robust, way to do this? Ideally, it would be database platform independent, but for now I am only using SQL Express.
Also, I have seen some forum items on problems with LV 8.2 databasevariant to data vi applied to date-time values. Does 8.2.1 fix this?
