A part of my code converts a time stamp into a string. Another part will have to read this string and convert it back to a time stamp. However, when I run this quick example I've created, I get an error. Does anybody know what I'm missing? It worked, thanks! I guess a 2-digit year is not enough information to reconstitute a full absolute TS I'm sure you have it in a specific format, but if you want to go with the ISO standard for having time as a string.

By default, datestr returns text in the format, day-month-year hour:minute:second. If hour:minute:second isthen the text returned has the format, day-month-year. While datestr returns text representing dates and times, it is recommended that you use datetime values to represent points in time, and then convert them to text using the charcellstror string functions.
The datestr function returns a character array with m rows, where m is the total number of date vectors in DateVector. The datestr function returns a character array with m rows, where m is the total number of date numbers in DateNumber.
You can use formatOut with any of the input arguments in the previous syntaxes. All dates and times represented in DateStringIn must have the same format. This language is the language you select by means of your computer's operating system. If you leave 'local' out of the argument list, datestr returns text in the default language, which is US English. Use 'local' with any of the previous syntaxes.
The 'local' argument must be last in the argument sequence. The use of AM or PM in the formatOut output text does not influence which characters actually become part of the text; they only determine whether or not to include the characters.
Call datenum inside of datestr to specify the format of the input text representing a date. Convert multiple character vectors representing dates by passing them in a cell array. All input dates must use the same format.
Date vectors, specified as an m -by-6 matrix, where m is the number of full six-element date vectors. Each element of DateVector must be a positive or negative integer value except for the seconds element, which can be fractional. If an element falls outside the conventional range, datestr adjusts both that date vector element and the previous element.

For example, if the minutes element is 70then datestr adjusts the hours element by 1 and sets the minutes element to If the minutes element is - 15then datestr decreases the hours element by 1 and sets the minutes element to Month values are an exception.
Example: [,10,24,12,45,07]. Format of the output representing dates and times, specified as a character vector or string scalar of symbolic identifiers or an integer that corresponds to a predefined format. If you do not specify formatOutthen datestr returns text in the default format dd-mmm-yyyy HH:MM:SS day-month-year hour:minute:second.
The following table shows symbolic identifiers that you can use to construct the formatOut character vector. You can include characters such as a hyphen, space, or colon to separate the fields.
The symbolic identifiers describing date and time formats are different from the identifiers that describe the display formats of datetime arrays.I was wondering if anyone knows of a way in which one can convert a time and date string that is read from a.

The reason I ask this is because I need to calculate the time between cycles on a certain machine. I am thinking that the best way to approach this problem is to convert the string into a time stamp of the number of seconds from am. Then it'll just be simple arithmetic However, I have not figured out a way of doing this conversion.
Is there a function that I am not aware of? If anyone can figure out a better, more efficient way of solving this problem, I more than welcome the criticism and suggestions.
To easily convert the time string to a time stamp, create a time stamp control with the same formatting as the time string. It is like copying the string into the control. LabVIEW convert the value automatically. I am still quite new to labview, so I was not sure how to create the time stamp control.
Now that I have figured that out, how do I actually go about formatting the control though? This is 8 years old, but still a very useful hint!!! So using a TimeStamp indicator instead of scan from string. I'm not sure if that is the intended use of a control. These days, no, but back in Scan From String didn't know how to parse a time string into a time stamp.
I believe that was added in 8. And just to clarify Ton's point - you can input the same format string into a Scan From String function and get out a time stamp.

How can I change this? I am taking measurements from a counter input, which does not include timestamps, how can I add these?

If you are acquiring more than 1 sample in the DAQ Assistant, only one value of time will show up for all the samples that you acquire. The resulting measurement file will have one time stamp at the beginning of each measurement set. A screenshot is shown below.

However, I apparently need to convert my array of U64 ints to an array of strings, as it is an array of strings that is used to populate the Menu Ring. It should even accept an array. I'm not sure if it will work on U64 numbers, because I seem to have a vague memory of it coercing number to I32, but it probably will. In any case, if you want the actual value of the ring control to be the number you want, be sure to change the representation of the ring control to U Format Into String seems to work although it won't accept arrays, so you'll have to loop over it.

Message 1 of Re: Convert timestamp to string with milliseconds showing. Knight of NI. Message 2 of Trusted Enthusiast. Message 3 of I had a long, incorrect, post. Forgot all about doing it that way. Message 4 of Message 5 of NI Employee. I'm not sure how different the values would be but they indeed are coming from two different sources.I have an application that needs the UTC as a timestamp. The output of this gives me the UTC in a cluster.
This is shown in the upper branch of the VI above. The output shows me the correct UTC. This is shown in the bottom branch of the VI above. I expected the output of this to give me the UTC as a time stamp.
Here's the problem: for some reason, the Time stamp output is 1 hour ahead of the real UTC. Can anybody explain this? Any workaround? Go to Solution. Be careful; the code is doing something a little different what you think it is doing, and won't work correctly during daylight savings time transitions. LabView timestamps the underlying numeric data on the wire are always in UTC. You can verify this by casting a timestamp to a double.
If the problem is "how do I am make the timestamp control display UTC? Non-obviously, this setting applies to constants also.
If you set a constant using the default localtime view, then quit LV, change your timezone, and restart, the constant will appear to change. It hasn't really changed, in that the underlying number-of-seconds-since is still the same, it's just displaying it differently. The problem with the code above is that it says "display a localtime that has the same numeric digits as the current UTC time".
It modifies the time on the wire to represent a different time than "now"; it's "now" offset from "now" by your TZ offset. The second is doing it this way will work "most of the time" but it has weird quirks ask me how I know! United States. Turn on suggestions.
