how to convert time from second to hh:mm:ss using CVI

how to convert time from second to hh:mm:ss using CVI?

Can anyone advice?

[RobertoBozzolo]

Please be more specific: do you want to convert

• A time in some standard format (e.g. number of seconds since midnight, January 1, 1900)
• A interval in seconds in the corresponding h:m:s format (e.g. 63930 sec => 17:45:30)

In the first case functions in Time Related Functions class in the User Interface Library can be of help, specifically FormatDateTimeString

In the second case you'll have to develop your own function. I have a very simple one I can share if you're interested to.

hi

thanks

ya this is what i need

"A interval in seconds in the corresponding h:m:s format (e.g. 63930 sec => 17:45:30)" can share this ?

Here it is. As I told you, it is very simple:

//----------------------------------------------------------------------
// Function secToHMSstring ()
//----------------------------------------------------------------------
/// HIFN secToHMSstring ()
/// HIFN The function takes an amount of seconds and returns a string with
/// HIFN the corresponding value in H:M:S format
/// HIPAR sec/Value in seconds to convert
/// HIPAR verbose/If True use "hms" separators; if not, use ":" separator
/// HIPAR string/The output string. It is responsibility of the programmer
/// HIPAR string/that the string is large enough to keep the resulting text
/// OUT string
void secToHMSstring (int sec, int verbose, char *string)

{
	int     hh = 0, mm = 0, ss = 0;

	if (sec >= 3600) {
		hh = sec / 3600;
		sec -= hh * 3600;
	}
	if (sec >= 60)
		mm = sec / 60;
	ss = sec - mm * 60;

	strcpy (string, "");
	if (verbose) {
		if (hh > 0) sprintf (string, "%s%dh", string, hh);
		if (mm > 0) { if (strlen (string)) strcat (string, " "); sprintf (string, "%s%dm", string, mm); }
		if (ss > 0) { if (strlen (string)) strcat (string, " "); sprintf (string, "%s%ds", string, ss); }
	}
	else {
		if (hh > 0) sprintf (string, "%s%d:", string, hh);
		if (mm > 0) {
			if (strlen (string)) sprintf (string, "%s%02d:", string, mm); else sprintf (string, "%d:", mm);
		}
		else if (strlen (string))
			strcat (string, "00:");
		if (strlen (string)) sprintf (string, "%s%02d",  string, ss); else sprintf (string, "%d", ss);
	}

	return;
}
