How to set properly struct tm and timezone in C++?
Hi, I'm trying to create a time_t variable which contain the date that
So, for example, I tried this code:
struct tm timeptr;
timeptr.tm_sec=0; /* seconds after the minute - [0,59] */
timeptr.tm_min=Minuto; /* minutes after the hour - [0,59] */
timeptr.tm_hour=Ora; /* hours since midnight - [0,23] */
timeptr.tm_mday=Giorno; /* day of the month - [1,31] */
timeptr.tm_mon=Mese; /* months since January - [0,11] */
timeptr.tm_year=Anno-1900; /* years since 1900 */
timeptr.tm_isdst=-1; /* daylight savings time flag */
t...Write to Measurement File: Time has minutes and seconds. Where are the hours?
I have dynamic data acquired by Express VI: DAQ Assistant from a CompactDAQ and wired to Express VI: Write to Measurement File. In the resulting text file in the header the Date is recorded correctly in DD/MM/YYYY format. The Time field should be formatted HH:MM:SS.XXX but all I see is MM:SS.XXX. Is there a setting I should change to see the hours?
Found the answer, sorry. Excel formatting issue. Not LabView after all.

...Showing the difference between two times in Hours, Minutes and Seconds
Brendan Reynolds posted the following function a while back ago:
Public Function HoursMinutes( _
dtmStart As Date, _
dtmEnd As Date _
) As String
Dim intHours As Integer
Dim intMinutes As Integer
intMinutes = DateDiff("n", dtmStart, dtmEnd)
intHours = intMinutes \ 60
intMinutes = intMinutes Mod 60
HoursMinutes = CStr(intHours) & " Hours and " & CStr(intMinutes) &
I was wondering if anyone could modify this so it showed seconds as

How do I plot time related data on a Y/time ax? the data is in a
2x4096 double with one row of date time stamps in the excel date time
format and one row of data. I can plot them both, but the excel date
time is displayed in mumbers.
I am not familiar with the excel date format but google says it uses
1900 as a base year (so 01/01/1900 = 1). Matlab uses 1-jan-2000 so
you will need to make the necessary modifications to the excel date
number column and then use datestr to convert the numbers to a date
string of your choice.

Sorry should read 1-jan-0000
Dan Pearc...if time = 3 seconds, how do i set the values of the time steps 0,0.1,0.2,0.3,0.5,1.0,1.5,2.0,3.0,5.0 to -9999 from time =3 seconds
I have 18 inputs (arrays) which contain certain statistics and if time = 3 seconds, set the values of time step 5.0 to -9999.0.
I was wondering if there is an efficient way to do this without using a lot of case statements?
it's not really clear to me what you want to do...
I suspect: you have an array containing values and you want to output
them with a fixed timing of 3 seconds: you should use a for loop
autoindexing trough your array and sending the value to your
indicator/output/whatever. Put a "wa...Convert Seconds to hours:minutes:seconds

the Convert function to get my field converted to the format: HH:MM:SS ?
The field with the seconds in is called: "Diff"

7683 seconds = 02:08:03
is there an easy way to accomplish this?

Well, assuming you know how to arithmetic, conversions, and string
concatenation (and if not, check out http://pine.fm/LearnToProgram/),
all you're missing is how to pad with zeroes.
I do talk about the rjust method, but not that you can use it to pad

I've been trying to write an elapsed time to a spreadsheet file in an hours:minutes:seconds format, but the time is displayed in a floating point value of seconds..
how can I write to a spreadsheet in an hours:minutes:seconds format.
I often use a subVI that converts Seconds to Hours, Minutes and Seconds. Use the Quotient and Remainder function to divide your elapsed time by 3600, 60 and 1. You can then convert those values to a modified string and use the Write to Spreadsheet File. As Dennis said, newer versions of LabVIEW...php.ini sets max time to 90 seconds, yet I get a "Max execution time of 30 seconds exceeded"
This is weird. When I use getId3 to try to read meta tags out of
multimedia files, I get this error:

getid3.lib.php on line 54
But if I run phpinfo(), I get this:
max_execution_time 95 95
and if I ssh to the server and look in php.ini, this is confirmed:
max_execution_time = 95 ; Maximum execution time of each script,

Is there a simple function call within "C" that I can use to convert
number of seconds (keep in mind this may be a type longlong and has to
work on UNIX and NT) into Days, months, Hours, Minutes and seconds.
If anybody can provide me with an example I would be very grateful.
Thanks in advance for all that answer this post.

I have a table that stores elapsed seconds as a numeric value. There is
a PHP script that displays data from this table onto a web page. What
is the best way to display the elapsed time in an HH:MI:SS format?
Obviously the to_char function only works on dates, so I am not sure
how to go about this. Do I need to create an internal PL/SQL function
that is called from my PHP SQL?

I have been doing a bit of work lately with Windows Enhanced
Metafiles. The structures for these are defined in an include
wingdi.h and for most structures there are corresponding GDI get/set
functions. Imagine for a minute that you wanted to write basic get/
set functions in C from scratch with as little work as possible. It
seems like it should be (largely) possible to do so automatically by
recursively processing the structs. This cannot be an original idea,
has anybody ever seen this done before?
This is what I mean. starting from lines like these in the header
