public class TaskA extends HttpServlet
public void doPost(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        java.sql.Date Taskdate = new java.sql.Date(System.currentTimeMillis());

i am using DATETIME datatype in mysql.
whats a problem in my code.

You might want to use TimeStamp and not java.sql.Date which by definition does not include time.
You might also want to close PreparedStatement and Connection in your code.

How to get system date and time?

Can someone show me a code on how to get system date and time.
Thanks!

there is one really easy way to get system time, the api gives a great example of code on this. use gregorian calendar, which you'll find in the api under GregorianCalendar. You only need to create one instance of GC, ie Calendar time = new GregorianCalendar();
you save seconds, minute and hours into int values, so you don't have to access the system time every second, you can create a thread which adds one to the int second value, if oyu see what i mean, for example, i have saved the hours, minutes and seconds as int values;
int hour, minute, second;
i can then create a thread (Thread thread = new Thread(this) and run it like:
Calendar time;
int hour, minute, second;
Thread thread = null;
public MyTime() {
hour= time.get(Calendar.HOUR_OF_DAY);
minute = time.get(Calendar.MINUTE);
second = time.get(Calendar.SECOND);
if(thread == null) {
thread = new Thread(this);
thread.start();
public void run() {
Thread t = Thread.currentThread();
while(thread == t) {
thread.sleep(1000);
second++;
if(second > 59)
minute++;
if(minute>59)
hour++;
formatTime();
public void formatTime() {
second = (second > 59? 0 : second);
minute = (minute > 59? 0 : minute);
hour = (hour > 23? 0 : hour);
System.out.println(hour+":"+minute+":"+second);
public static void main(String[] args) {
new MyTime();
I know this looks like gibberish but it should work. If not, try to fix the problem, i have written from memory really but i guarantee you, this gets the time then every second, simply adds one to the second and then formats time. You can also access the day, month and year then format them using the above code. I don't like giving code since you should really do these things yourself but it is 2:04am, i have nothing better to do and i am not tired so i did you a favour - i have become what i always did not want to, someone ho stays upall night writing code.

Automatic file generation using system date and time

Hi guys,
Iam trying to generate a path for file creation automatically using System date and time. I am running into errors with respect to special characters in filename. I am trying to parse the string to get date and time without the '/' and ':' but have not been successful. is there a better way to do it? Please help! I am trying to avoid a dialog box for user to enter a filename.
Thanks!

I may not be perfect, but I'm all I got!
Solved!

How can i pass system date and time in update mode in tabular form.
Thanks

Hi,
You just create a trigger on the table on which you build your tabular form:
e.g:
CREATE OR REPLACE TRIGGER "AUDITING"
before insert or update on "MYTABLE"
for each row
begin
    if inserting then
        :new.created_on := localtimestamp;
        :new.created_by := nvl(v('APP_USER'),user);
    elsif updating then
        :new.updated_on := localtimestamp;
        :new.updated_by := nvl(v('APP_USER'),user);
    end if;
end;Regards,
Fateh

Extracting Time without using the System Date and Time

Hi, can I know how to process a task at this particular time eg. 6PM everyday without using the System Date and Time..
Do I need to use a Timer to get this done or is there any other solution to do this? Can give me a few hints? Thanks in advance =D

You could use a timer...assuming you had some good reference point when you started so you would know that from your starting point it's now 6pm.
I thought I saw you asked this question once already...and you were given a similar answer....I think by Sylviae?

How to get the date and Time?

Hi,
I am using Jdev 11.1.2.0.
I had one database table. In that table one variable as bgnDtm and the datatype as oracle.jbo.domain.Timestamp. In my Impl class I declare one variable as beginDate(DateType as oracle.jbo.domain.Date).
Now I am using the conversion as beginDate=(Date) SampleVO.getAttribute("bgnDtm ");.If I using this scenario I got the Type cast error. so how can I separate Date and Time value.
So how to do. Please provide some suggestions.
Regards,
Ragu.

you can get the time value either from oracle.jbo.domain.Timestamp or from oracle.jbo.domain.Date
oracle.jbo.domain.Timestamp timeStampDate = (oracle.jbo.domain.Timestamp) SampleVO.getAttribute("bgnDtm");
Time time;
        try {
            time = timeStampDate.timeValue();
            System.out.println(time);
        } catch (SQLException e) {
            e.printStackTrace();
        java.sql.Date sqlDate=timeStampDate.dateValue();
            oracle.jbo.domain.Date jboDate=new oracle.jbo.domain.Date(sqlDate);
        Time timeValue = jboDate.timeValue();
        System.out.println(timeValue);Edited by: M.Jabr on Dec 23, 2011 1:55 PM

Bill,
reviewing the thread Dennis linked (thanks for that) reveals that it is the same account which opened this thread here three month later.
What bothers me is the fact, that the past thread is marked "solved" even though it obviously isn't. Or the OP is trolling us.....
Nevertheless, it seems like systematic error. Connected to specific machines.
What makes the machines where the time stamp issue occurs "unique"? If there are several, is that source really "unique"?
Most obvious reasons would be:
- Language settings (possibly the infamous "dot-comma-issue")
- Time zone settings (e.g. what happens if you switch Ulaanbaatar to Perth or maybe even some US time zone?)
- Missing hotfixes for Win and LV
- Is the system running as virtual machine vs. "native"?
Not so obvious differences:
- Specific CPU type
- Motherboard/BIOS
- LV ini settings
There are tons of other possible reasons (e.g. corrupt LV installation), but these are the ones i came up with within a couple of minutes....

How to find the Date and Time of Modification of Column in aTable?

Hi all,
Do you know how to find the Date and Time of Addition of Column to a Particular Table?.
I know however, How to find the modification time of the Table. Using the below Query :
Select Object_Name, to_Char(Last_DDL_TIME, 'DD-Mon-YYYY HH24:MI:SS') Last_DDL from User_Objects where Object_Type = 'TABLE';
Object_Name
Last_DDL
Employee
20-Aug-2013 09:23:03
I wanted to know the Creation or Modification Date and Timestamp of all columns of Employee Table?. Is it possible at all. If possible, How to get it?.
Regards,
Bhaskar M

I agree with you on that. Since its a development enviornment I can remove the column but that not my point here.
My whole purpose it to know whether we get the Column's Creation or Modification DateTime.

How Production Order finish date and time is being comptued by SAP?

Hello Expert,
How Production Order finish date and time is being comptued by SAP? for example, we create a Production Order via CO01, the basic start date is 29.09.2008 and time is 04:00 it gives us basic finish date is 29.09.2008 and time is 13:28.
how does SAP compute the time 13:28 as it finished time
Please explain me briefly.
Thanks
Ryan

Hello Guys,
When we create Production Order in R/3 the time is calculated by routing but it is extended at SetUp machine time. It is not correct?. SetUp imachines time used only for first Production Order for the same product and it is plan manually, for others Production Order we need calculate time for production without SetUp machine time being pick up to compute finish time. how could we achieve this? only those Machine time will be check.
thanks

How do i show date and time info of videos in Iphone as they appeare before import in iPhoto?

How do i show date and time info of videos in Iphone as they appeare before import in iPhoto? or even as they appear on the iPhone itself? The selection on tool bar for show info is greyed out.

Welcome T G Brown to the  iMovie boards..
the socalled timestamp is within the imports.. if you select a clip in iM and hit the key combo Apple-I, you can see recording time and date.
unfortunately, this info isn't delivered to any software. Bruce Gee (geethree.com, excellent plug-in maker) told us, there's no 'API' he could use for such a feature...
same on the pro side, read this discussion at the FinalCutExpress boards:
http://discussions.apple.com/message.jspa?messageID=7982935
Forum member Ian offers a solution with a 3rd party app ....
so: pen&pencil and typing timestamp manually into any 'Title' seems to be your only option...

Samsung Galaxy S 5 - using automatic date and time

Using automatic date and time sets the date to November 27, 2014 instead of the correct date of September 25, 2014. What's going on? I haven't ever had a problem with this setting before.

Clear phone system cache & place phone in Airplane mode then do a power down (not a restart) of the phone. Next remove both SIM card and battery & wait for 1 minute or so. Then reinstall the SIM & battery and power phone on. If your signal is strong this should reset your data channel to the correct time.
