Unix time vs oracle time

I'd like to know what advantages there are for using the different time formats?
I am currently redeveloping an old database and the date/times can be found in Julian, Epoch, and YYYYDOY formats. Is there any preference for which format i should convert the date/times to?
If you suggest oracle datetime, which oracle format and how much accuracy do these have?

If date data is being stored in something other than Oracle date formats, there's probably a problem. You can convert an Oracle date to just about any possible character format.
Oracle dates store dates to the second. You can use the timestamp data type in 9i if you need sub-second resolution.

  • UNIX time to Oracle time

    Hallo,
    I am acquiring the data for my reports in a UNIX evironment using embedded SQL.
    Therefore I am searching for a function that converts the UNIX time to ORACLE time. Currently I am doing the conversion via a string representation but I would prefer a function that does it on a binary level.
    Thanks a lot - Ulrich

    maybe (using the link provided) ;)

  • Get date from Oracle when local time zone is different from Oracle time zon

    Hi!
    Local machine time zone= +2
    Oracle time zone= +1
    I set date to Oracle using java.sql.Date.
    From application I save date at 00:30 clock and send e.g. 28.06.2002, but in Oracle date is save as 27.06.2002 01:00 (hour=01 , I suppose that is because java.sql.Date hasn't time the Oracle set it time = time zone=+1) And when I get date from Oracle I get incorrect date. In SQL I don't use date masks. Maybe solution is to use java.sql.Timestamp object (when save date to Oracle) instead of java.sql.Date?
    But if I save date at e.g. 01:00 clock and send e.g. 28:06.2002 in Oracle, date is save as 28.06.2002 01:00 and when I read from Oracle I get correct date.
    Thank you.

  • Parse times in Oracle 11G

    Has anyone else experienced extremely long parse times for Oracle 11G versus 10G? We are experiencing at least a 10 times increase in the parsing of our SQL statements. This is causing our customers to complain when running reports which contain several SQL statements that aren't in the SGA due to the infrequent use. I have opened a Service Request and development stated that this is to be expected with Oracle 11G due to the new optimizer features. I have tried to disable the features by settting the optimizer version to anything but 11G and no setting has helped. To make thing even worse, this increased parse time is on a new server that should be 2.5 times faster than the server that is running the 10G database. I do get at least a 2.5 times increase, larger if I/O intensive, in almost every other aspect of the database except for the parse times.

    I wondered what the resolution was to this issue. We currently experiencing this will our Oracle 11.1.0.7 database with a small but important set of queries and it seems to be getting worse. We first noticed it with a query that went from taking 3.5 seconds to 7 seconds. A SQLTrace / TKProf revealed that 99% of the time was being spent during the parsing. A second similar query that brings in more data is taking around 1.5 minutes to parse then only a few seconds to actually execute. These are queries that are part of on online web transaction so this is not acceptable. We are able to replicate the behavior in multiple database instances.As a starting point it would be interesting to see the tkprof output from :

  • Problem with getting current date and time using oracle.jbo.domain.Date

    I`d like to get current date and time using oracle.jbo.domain.Date method getCurrentDate(), but it always return current date and 12:00:00. I also need to get the current time.

    I think you should use java.sql.Timestamp domain.

    Just you need to change in forms.
    Change the Data type Date to Datetime
    to show only time, use format mask.

  • Is 000001010000z a valid date time in Oracle?

    Hi,
    When working with Open LDAP connection from Oracle, I need to set and remove the value '000001010000z' for locking and unlocking the user account respectively. This is working fine. However, for some calculation, I need to convert this value as a date value which I couldn't do. Is this a valid date time in Oracle? If so how to convert it as a date value.
    Oracle version: 10g R2
    Thanks,
    Natarajan

    Thanks, Mithun for your answer. We have the same issue, as an user, we can lock an account using the special value, but unable to unlock using the same user. I have reported this to our LDAP administrator.
    Regarding my question using this special value as a date value in oracle, though it is a valid date in the LDAP system, we cannot convert this as a date value in Oracle.

  • Problem while inserting Date/Time in Oracle Database

    Hai,
    i want to insert the date and time in a date column. here, i am using java.sql.Date and java.sql.Time to assign the date in Prepared Statement.
    PreparedStatement psmt=con.prepareStatement("insert into test(ex_date) values(?)");
    java.util.Calendar c=Calendar.getInstance();
    c.set(2002,2,21,10,10,00);

    psmt.clearParameters();
    psmt.setDate(1,d);
    psmt.setDate(1,t);

    Above program is inserted the Date and time in the database as the following "1900/2/21 10:10 AM"
    but i am giving the year as 2002. it inserted the year as 1900. what is the problem with the code?
    please let me know
    Thanks in advance.

    psmt.setTime(1,t); // Last time i put psmt.setDate(1,t);
    psmt.executeUpdate();
    and, the getTimeInMillis() method is a protected method in java.util.Calendar class. how can we use it
    please give me some other idea to insert the date and time in oracle database.
    Thanks in advance

  • VI to convert Unix time to standard time?

    hi,
    I am in need of a VI to convert Unix time to Standard time?
    eg: Unix time: 1268845177 in seconds
    Standard time: GMT: Wed, 17 Mar 2010 16:59:37 GMT
                            Your timezone(U.S):
    Wednesday, March 17, 2010 10:59:37 AM
    I have the calculation but not full formula.
    Unix time is in seconds from Jan 1,1970, 00:00:00 UTC, starting at 0 counting forward.
    When 1268845177/86400 = 14685 days.
    86400 = 60*60*24 seconds
    But how to convert the 14685 days and relate to the current date, how it should be done?
    Either the formula or a VI to convert Unix time to standard time will be a help.
    Regards,
    Arvinth

    Timestamps and the PC clock vs. time on the net are different and I'd say somewhat unrelated concepts.
    You are worried about accuracy of the current time.  Timestamps have nothing to do with current time, but are a way of identifying and particular moment in time.
    Yes, the PC clock gets its time from the net assuming the time server settings are all set properly.  Even the correction of the current PC time may not happen exactly when the leap second gets inserted.  It may be some time before the PC resynchronizes with the net time.  The PC doesn't know if the existence of when a leap second will occur.  And neither does the LabVIEW timestamp.
    Here is an example.  According to http://en.wikipedia.org/wiki/Leap_second, a leap second will occur at the end of June 30 of this year UTC.  Since my clock is eastern daylight time at that date, I put together an example for 8pm on June 30  (UTC +4).  You'll see that the 3 values (a second before, the exact time, and a second after) show they are all 1 second apart.  There is no extra second accounted for.  So in real life the time a second after  vs. a second before are actually 3 seconds apart, but LabVIEW only show 2 seconds.  Feel free to play with the attached snippet for different timezones and daylight savings time and all of that.
    I don't think you really have as big of a problem as you are trying to investigate here.  If your timing needs are that critical where you need accuracy of the current time to better than a second, then you shouldn't be looking at LabVIEW timestamps, PC time clock, or internet time at all, but look at a high accuracy timing source perhaps based on a GPS clock.
    Unless you have a particular test planned to run over the expected point of time where a leap second is inserted, then you shouldn't have to worry.  Even if you do have a test run over the leap second, you probably don't need to worry either.  If the test is based on a waveform datatype, then you have a T0 timestamp, and a dT that will keep track of all the individual data points accurately.

  • SAP Time zone vs oracle time zone

    Hello Experts,
    I am confused by SAP's system time zone setting and oracle database's time zone setting.
    Can I change SAP time zone setting without affecting the database time? Are they the same thing? Must I restart SAP / database / server after the TZ change at SAP-level to effect it? Is OS time zone = database time zone = SAP time zone?
    Has this anything to do with database timestamp?
    Pls advice.
    Regards,
    Ernesta
    (I promise to award full points for best answer).

    Hello ernesta,
    As I know, SAP's time is a mathematic calculation on the server/database's time.
    This calculation is called time zone. Using transaction STZBC you can change your country's settings (for example CET+2 and etc). After the changing you'll have to restart the SAP instance.
    You can set time zone setting to specific users via transaction SU01.
    Furthermore, I suggest you to read several notes, maybe they could help you in the future:
    Note 184992 - Country/time zone assignment not correct
    Note 129266 - One hour time deviation
    Note 102088 - End of daylight saving time: the "double hour"
    Note 081950 - Time zones: local date in dialog and in RFC
    Best Regards,
    Dimitry Haritonov

  • Why can't read access log file in real-time? (Oracle Weblogic Server 10.3)

    We can't read access log file in real-time. If access log is rotation to new file so can read access log file but can't read real-time.
    *** Oracle Weblogic Server versions 10 R3

    what's your meaning? try this command "tail -f access.log".
    Threre is a buffer about 8K for WebLogic to write the access info into the log files, so you can't see the access info untill the buffer is full.

  • Oracle Time and Labor - Change and Late Audit

    Dear All,
    We are using Payroll Layout and Single Day period.
    Timecard has only Hour Type (Regular Time, Overtime & So on.) and In / Out.
    We have Swipe Machines. Employee Swipes In & Out. Every night these entries are deposited in OTL with Submitted mode.
    Next day Employee is allowed to modify these entries in accordance with Time Policies.
    For e.g. Timecard shows 08:30 to 19:30 as Regular Hour. Employee can modify 08:30 to 17:00 as Regular Time and 18:00 to 19:30 as Overtime Hour Type.
    Now the problem is Approver would like to know exact change, as what was the Original Entry and What is the modified entry.
    Is there any way to achieve this?
    Can Change and Late Audit work on Payroll Layout?
    I am unable to find Payroll Change & Late Audit Layout. Only Project Change and Late Audit Layouts are available and we are not using Project.

    Hi 864434,
    An easier way would have been to use Earning policies.
    You can define rules which would automatically split the earning types to Overtime etc..
    This is a very simple setup too.
    Some examples here -
    Oracle Time and Labor (OTL) OTLR California Overtime Policy Setup and Examples [ID 1451080.1]
    This way, the layout would show what the employee has actually worked and how the rules are applied to split it, all on one page.
    But if you don't want to go that route..
    Can you not use the data from the swipe machines ?
    I guess you would load the data into an temporary table.
    So you can write a discoverer report which would show the actual times for each employee.
    On the layouts, there are only some predefined ones.
    Others, you will have to create on your own(may be by customising a seeded one)
    Hope that helps,
    Cheers,
    Vignesh

    Hi
    We are not implementing any kind of flex Time.
    Are you aware of how to setup OTL to record time worked in Days, and how that can be transported to Oracle Project.
    The module is configured to setup in Hours.
    Any ideas?
    Could you highlight any documents that will simplify the process of a basic OTL setup
