Formatting a string with time stamp and double precision numbers

%s\t%f\r%f
This is a format string that I have in old code that I've decided to change. Problem is I cannot make sense of the string codes in my own old code! Let me explain what I want, and hopefully someone can explain how to do it.
I am using the format into string subvi to merge a time stamp (formatted as %m%d%Y%H%M%S%5u) and two different double precision numbers. This string is then wired into the Write Characters to File subvi so that I can record data as a .txt file, and open it in either Matlab or Excel. There is a minor problem with the string format above because in excel the first time stamp entry is blank, and the first loop only gives the two double precision numbers withouth the time stamp - the time stamp appears in the next loop (probably a looping issue and not due to the string format, but if you see differently please let me know). Now what I want to do is 1. potentially fix that problem and 2. add some more doubles.
1. Is there a string format issue that is evident that I am not seeing that causes the time stamp to be formatted into the string after a carriage return? Or should I be looking at looping issues?
2. How do I add another one - three floating point numbers (double precision)? Are the \'s marking different numbers in this string constant? Or is it the %? I can't find any information about the \'s, but I see that % begins the format specifier.
Ideally, I want these data in the following columns: Date, Time(absolute), FP, FP, FP, carriage return for the next loop (FP is floating point double precision number).
Thanks,
Brad

Hi JonN,
Here there is no need of string concordinate function (in your code), the same result you can find if you connect the output of the format string to shift register, and shift register in data to initialize string connector in format into string function.

Converting time stamp to double

Hello,
I am currently using the write to spreadsheet file.vi to save data.
It looks something like this:
I also want to add the date and time stamp into the saved data but do not know a way of converting a date and time stamp to 'double format'. When the date and time stamp is in teh double format I can easily concatenate the data stream with the 'date and time' in a 2-D array.
Thanks,
Nevica

Extract date/time stamp and modifier name from memo field

I need to extract all date/time stamps and modifier name strings from the Work Log memo field - or conversely, filter out all of the comments after the date/time modifier strings. I have the string extract but it only extracts the first one. I need to loop until all are found - how can I do this? The memo field will look something like this:
3/5/2009 3:32:05 PM John Doe
Comments - string can be any length
3/4/2009 12:35:43 PM John Doe
Comments - string can be any length
3/4/2009 12:28:17 PM Jane Dough
Comments - string can be any length and include date format 2009-06-04 14:20 CST.
3/4/2009 12:27:47 PM Mary HadaliddleLam
Comments - string can be any length
3/4/2009 12:26:55 PM Lamseedivy
Comments - string can be any length
3/4/2009 12:15:22 PM Mareseedoes
Comments - string can be any length.

Here is a formula that will strip all 'comment' and blank lines and puts the datetime stamp and user names into an array. You have to manipulate the elements of the array to further separate the datetime stamp and user name if required.
// Declare two indices
numbervar i := 1;
numbervar j := 1;
// Split each row of the memo field into an array
// if chr(10) does not work then try with chrw(13) or chr(13)
stringvar array x := split({Sheet1_.Comments},chr(10));
// Declare a holding array
stringvar array y;
// Declare the size of the new array to be equal to the elements in array 1
redim y[ubound(x)];
// Copy only if the first word of each element of array 1 is neither "comments" nor a blank line
for i := 1 to ubound(x) do
if split(x<i>) = 'comments' or x<i> = '' then
else
(y[j] := x<i>;
j := j + 1;
// Compress the new array to eliminate the last blank element
redim preserve y[j-1];
// Joining the elements of the new array and the number of elements for display
join(y,chrw(13)) & chrw(13) & ubound(y);
With your example, this formula will return:
3/5/2009 3:32:05 PM John Doe
3/4/2009 12:35:43 PM John Doe
3/4/2009 12:28:17 PM Jane Dough

3/4/2009 12:26:55 PM Lamseedivy
3/4/2009 12:15:22 PM Mareseedoes
6.00
Make sure the "can grow" option is checked to display the results and also check for case sensitivity of "comments".

Inserting Current Date with time stamp in oracle database

Hi Experts,
I want to insert the current Date and time stamp in a field in the Oracle Database Table.
I am able to insert date but i am not able to insert the date with time stamp. Any Suggestions??
Thanks
Naveen

Naveen,
Do you want to get current date (from sysdate) with a specific format or transform a value containing a date/time value to insert it in ORACLE ?
Usually, you insert current datetimestamp in a date field using this :
TO_DATE(sysdate,'dd/mm/yyyy hh:mi:ss')
you may have to tweak the format pattern ('dd/mm....') according to your needs
if you want to transform a date, use something like this:
TO_DATE(your_date,your_format)
but make sure your format is compliant with your date, ie
TO_DATE('31/12/2008','MM/DD/YYYY') could raise error (litteral does not match) cuz ORACLE can't recognize 31 as a month pattern

Where clause with time stamp

Hii,
I have an issue with using where clause with time stamp. My requirement is to
select * from driver_on_policy
where last_change_datetime = '2001-03-06 19:00:06'
date is in this form 6/3/2001 7:00:06 PM
thnks
sam

If you want to use '6/3/2001 7:00:06 PM', then
where last_change_datetime = to_timestamp('6/3/2001 7:00:06 PM','DD/MM/YYYY HH:MI:SS PM')If you can use a literal string in ANSI standard YYYY-MM-DD HH24:MI:SS format, then just
where last_change_datetime = timestamp '2001-03-06 19:00:06' (That 'DD/MM' might need to be switched around to 'MM/DD' if you are in America.)

Partitioning an External 320gb drive for use with Time Machine and...

I want to be able to use my Western Digital 320GB external drive for use with Time Machine and to use as extra storage space on both my Mac and when I boot into Windows Vista.
Is this possible?
I was playing around in Disk Utility and would I partition the part I want to use for Time Machine with the Mac OS Journaled, and whatever I want as space for windows, use a MS - DOS format?
Has anyone done this before?
Cheers-

Unless you are using 64 bit version of MSWindows (64 bit XP/Vista), it won't be able to handle a disk with GUID partition table (GPT). Disks with Apple Partition Map (APM) or GUID partition table are the only ones that Time Machine will work with (not MBR disks). Note also that the MBR/APM/GPT are at the DISK level and not the partition level, so don't mix the format with partitioning scheme. Time Machine disks are meant to live in the Mac universe (for now, anyway) and sharing with the MSWindows 32-bit universe is not possible.

File name for append processing mode with time stamp

Hi Experts
we are doing file to file scenario using the processing mode as Append.
the requirement for us to append the files and we need to have new file name with time stamp added to the appended file.but in the processing mode of the file adapter either we can append or add time stamp. thatz the problem I am facing now.
we are doing file based processing not message based ,micheal blog regarding the dynamic file name is for message based not for file based.
Please provide your valuable comments.
Thanks
Faheem

Hi mohamed,
I suggest you to map the target source structure to the required filename u want, like for example ur filename is input26062008.txt means to the target structure u perform the following mapping
constant (input) concat with currentdate function --> concat with constant .txt --> map this concat to target. So u will get the filename u expected with the time.
Then in the communication channel u select the mode as append. Now ur requirement will get solve i think so. plz try.

TDMS viewer not showing data with time stamp

Need help with time stamping data in a TDMS file generated by DAQ Assistant.
When I use the TDMS Viewer, with the x-scale set to absolute time, the date starts at 1903. If I use Excel to look at the file the start time is correct (i.e. 2013).
Solved!

Bo_Xie, I have simplifed my VI and now able to display the correct time stamp. Thank for your time!

Apache Trinidad is running with time-stamp checking enabled.

Experts,
Contents of my web.xml file
<context-param>
    <description>If this parameter is true, there will be an automatic check of the modification date of your JSPs, and saved state will be discarded when JSP's change. It will also automatically check if your skinning css files have changed without you having to restart the server. This makes development easier, but adds overhead. For this reason this parameter should be set to false when your application is deployed.</description>
    <param-name>org.apache.myfaces.trinidad.CHECK_FILE_MODIFICATION</param-name>
    <param-value>false</param-value>
</context-param>When my application runs i get the following on the weblogic console
<ViewHandlerImpl> <_checkTimestamp> Apache Trinidad is running with time-stamp checking enabled. This should not be used in a production environment. See the org.apache.myfaces.trinidad.CHECK_FILE_MODIFICATION property in WEB-INF/web.xml
<UIXEditableValue> <_isBeanValidationAvailable> A Bean Validation provider is not present, therefore bean validation is disabled
Isnt it a bit strange ? Please advise what is wrong.
thnks
jdev 11.1.2.1

If you're talking about the integrated WLS, time-stamp checking is automatically enabled no matter what so that changes you make in the IDE can be picked up. It's nothing to worry about.

File with time stamp

Hi All,
I using RFC to file scenario ,in this when file is created it folder it is coming with date and time stamp.but i am not using add time stamp in processing paramerts.i have checked the file name in communication channel monitoring it is coming without timestamp
but in folder file is getting created with time stamp.
Regards

Hi Gangadhar,
In the receiver file adapter, under Processing tab, see the value of File Construction Mode.
This value should be Create instead of Add Time Stamp.
After making the changes save & activate the file receiver channel. The output file then will not have timestamp appended to its name.

My start up disc is full i have a macbook air, i back everuthing up with time capsule and have movies all my music libraries and photos onto that too so as i have free space, but my max still says my startup disc is full with "other"

my start up disc is full i have a macbook air, i back everuthing up with time capsule and have movies all my music libraries and photos onto that too so as i have free space, but my max still says my startup disc is full with "other"

First, empty the Trash if you haven't already done so. Then reboot. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
If you're using Time Machine to back up a portable Mac, some of the available space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.
To locate large files, you can use Spotlight as described here. That method may not find large folders that contain a lot of small files.
You can also use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Proceed further only if the problem hasn't been solved.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
Install ODS in the Applications folder as usual.
Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means.
When you're done with ODS, quit it and also quit Terminal.

Backing up Mac HD with Time Capsule AND an external hard drive

I am sure that this question has been asked one way or another but I can't seem to find the exact answer.
I would like to back up my Mac HD with the Time Capsule AND another hard drive essentially to create two backups. Should one fail, I still have another copy as a precaution. The Time Capsule will be my primary back up because my external hard drive is usually switched off and will only be turned on from time to time to perform "less frequent" backups.
With Time Capsule AND the external hard drive on, will Time Machine just update the backup on the external hard drive without becoming confused with the other copy on Time Capsule? In other words, can Time Machine distinguish between two different Time Machine Backup files and bring them up to date accordingly?
I understand there is an archive function on the Time Capsule, which would also serve the purpose. However, I am wondering if there is another way.
Thanks.

I don't think it's possible to configure Time Machine to back up to two locations without modifying its settings frequently.
You might consider using that external drive to hold a bootable backup. You can create such a thing with either of the utilities SuperDuper! or Carbon Copy Cloner. If you pay the registration fee for SuperDuper! (~US$28), there's a mode where it will back up only what has changed, which makes the backup operation run quicker. (Carbon Copy Cloner may offer a similar feature.)
