Convert date/time to a value in second

Hello,
I want to convert a basic date time variable into a numeric one corresponding to the time (in second) passed since January,1,1970 in order to put it in a SQL statment as a criteria.
Is someone able to help me ?
Regards

If you have an java.util.Date object you can call getTime() method on it. It will return milliseconds. Just divide it on 1000. Here is example code:
java.util.Date date = new java.util.GregorianCalendar(2001, 7, 6).getTime();
long seconds = date.getTime() / 1000;
//Your code
Best regards, Alex.

How convert date/time from xml in xdp(Designer)?

Hi, i want to convert date/time format from xml in Designer, date/time value in xml is NOT in common format YYYY-MM-DD (if is in a common format i can do this with pattern)
I have a "DateTime" Field in Xdp can get from Xml date and time:
In XML <DateTime>DD-MM-YYYY</DateTime> i want to convert in XDP in DateTime Field in "DD-April-YYYY"
Can i do this?

You can do this way..
Bind the date field to your XML tag.
Set the display pattern for the date field.
In the initialize event of the date field place the following code.
Set JavaScript as language.
var dtStr = this.rawValue;
var pos1=dtStr.indexOf("-");
var pos2=dtStr.indexOf("-",pos1+1);
var strMonth=dtStr.substring(0,pos1);
var strDay=dtStr.substring(pos1+1,pos2);
var strYear=dtStr.substring(pos2+1);
//Assign the formatted value to the Date field.
this.rawValue = strYear + "-" + strMonth + "-" + strDay;
Thanks

How to convert date-time according to the Time Zone the client

Urgent! Help wanted!
I extract a date-time field (which is GMT time) from the central database but I need to convert it accordding to the TimeZone of the user and also the so-called winter time and summer time in the local. Any one has any good solution?
Thanks.

Use a Calendar, Timezone and Locale objects like this,
TimeZone tz = TimeZone.getTimeZone("Germany/Berlin");
Calendar cal = Calendar.getInstance(tz, Locale.GERMAN);
long date = 0; // assign your central database value to this variable
cal.setTime(new Date(date));
Now you can use the Calendar object 'cal' to retrieve the time according to the set locale and timezone.
These objects provide tonnes of features for finding out timezones and day light savings times. So check out the APIs as well.
I hope this helps you out.

Convert date/time to HEX command and write to a bin file

Hello,
I have to do the following thing. I have the date/time string, let's say 08:45:23, 12.08.09, where the hour, the minutes, the seconds, the day, the month and the year represent hex number or in other words I have the following command:
Byte 0 - Byte 5
0x08; 0x45; 0x23; 0x12; 0x08; 0x09;
Now I want to write this command in a binary file in order to send thefile later throught serial RS232 connection.
Now, I am not sure whether I write the command in the binary file in the correct format. What I simply do is to write it as a string
("084523120809"). Is this the correct way. I guess no, because when transmitted it does not work as expected.
How can I write this string as a HEX command in the binary file?
Thanks for the replies in advance

Do you know the difference between decimal and hex values? It's not the same, that the whole point, and it's why it doesn't make sense. Decimal 32 is not the same as hex 32. These are two different values, even though they both have the digits "3" and "2". The hex value will be the same as the decimal value up to the value of 9. In your example the hour is 8. In decimal this is 8, in hex this is 8. The minutes is 45. That's decimal. In hex, this is 2D, not 45, as you claim in your example. Hex 45 is a completely different number (and a completely different "pattern").

Funny thing, look at the compareTo result....

Convert date/time to Unix epoch

I have thousands of date time stamps I would like to convert to Unix epoch ten-digit strings. That is, take some thing like:
Dec 9, 2005 10:24 AM
and convert to
1234567890 (only in the correct unix epoch time)
What formula can I use? I've found that this "=DATE(1970,1,1)+P2/86400" can convert a 10 string epoch time down to just a date correctly, but without time. But I need to go in the opposite direction, with the time included.
Using Numbers 09 ver 2.0.5 (368)

CP,
An up-to-date Unix Time would be provided by:
=DUR2SECONDS((NOW()-"1/1/1970"))
A somewhat more robust form would be:
=DUR2SECONDS(NOW()-DATE(1970,1,1))
If the time to be converted is in Cell P2, the expression would be:
=DUR2SECONDS(P2-DATE(1970,1,1))

Convert Data time stamp to Local Time

Hello,
I want to convert this input to local time EST.
Input:12/8/2006 10:23:00.000000000 PM -06:00
o/p: EST.Local Time

Is the input a string? A timestamp? If so, which flavor of timestamp? Something else?
Normally, you'd want to use a TIMESTAMP WITH LOCAL TIME ZONE data type for this sort of requirement, since it automatically converts data to the client's time zone. Assuming the input is a string and that the client's time zone is set to EST
1 select cast(to_timestamp_tz( '12/8/2006 10:23:00.000000000 -06:00',

Internationalization issue : convert date/time to GMT/UTC

We have our webservices running in websphere /oracle.There is this requirement to internationalize the application ...like
a) language .....
d)Internatiolization of time :
For this requirment I am planning to do the following.Service request with date will be converted to GMT before it is stored in database and the response back will be converted from GMT back to the time zone of the requester and have the application server/database server configured to UTC time.Is this a good strategy or is there a better one.
Thanks

Are you starting with a java.util.Date or perhaps a java.sql.Timestamp?
Then you do NOT convert them. You display them. You use SimpleDateFormat for that. You do not concern yourself at all with timezones exception in terms of creating a SimpleDateFormat. And that is ONLY an issue if you are creating the string (display value) on a server. If you are doing that you will need the client to provide you with a timezone. There is no magic way to get that from the client. If a client app is doing the display the the client is running in a client VM and that VM will already have a display format that might be suitable.
Conversely if you are receiving a timestamp value as a text value (say read it from a file) then you must convert that into a java.util.Date. You do that via SimpleDateFormat. The specifics of how you do that depends on the form of the text value.

Convert date time to file date time

Hi,
I have standard delphi function which conver datetime to filedatetime here is the description
function DateTimeToFileDate(DateTime: TDateTime): Integer;
Description
Use DateTimeToFileDate to convert a TDateTime value, which is the representation of date-and-time values used by the VCL, to a DOS date-and-time value.
For example, use DateTimeToFileDate to convert a TDateTime value to a
format that can be used as the Age parameter of FileSetDate. You may
also need to use DateTimeToFileDate to convert a TDateTime so that it
is compatible with the Time field of the TSearchRec record used by the FindFirst
and FindNext functions.
Lo returns the low-order Byte of the argument X as an unsigned value. X is an expression of type Integer.
Use Hi to obtain the high-order byte of an expression of type Word or Integer.
Note: Hi treats Integer as a 16-bit value, even if it is 32-bit.
This is the delphi code that convert the date
year=2003
month=5
day=28
sec=57
min=45
hr=13
msec=107
LongRec(Result).Lo := (Sec shr 1) or (Min shl 5) or (Hour shl 11);
LongRec(Result).Hi := Day or (Month shl 5) or ((Year - 1980) shl 9);
output Result is --> 784100796
Any help will be highly appreciated.
Thanks.

You use the java.util.GregorianCalendar to extract month, day, etc from a date.
Then you use the shift operator ('<<') to construct the number.

If you have an java.util.Date object you can call getTime() method on it. It will return milliseconds. Just divide it on 1000. Here is example code:
java.util.Date date = new java.util.GregorianCalendar(2001, 7, 6).getTime();

Problem converting Date time vanishes

Hi,
I am doing the following
String datstr = coform.getCourseDate();
LamLog.log(this,LamLog.INFO,"Date in insertRow is " + datstr);
LamLog.log(this,LamLog.INFO,"Date in insertRow sdf.parse(datstr) is " + sdf.parse(datstr));
java.sql.Date dt = new java.sql.Date(sdf.parse(datstr).getTime());
LamLog.log(this,LamLog.INFO,"Date after creating in insertRow is " + dt);
dt.setTime(sdf.parse(datstr).getTime());
LamLog.log(this,LamLog.INFO,"Date after conversion in insertRow is " + dt);
but the result I am getting is
Date in insertRow is 04/01/2003 09:30:00
Date in insertRow sdf.parse(datstr) is Tue Apr 01 09:30:00 EST 2003
Date after creating in insertRow is 2003-04-01
Date after conversion in insertRow is 2003-04-01
if you see after converting to sql.Date the time portion of the date vanishes. What is wrong??
Kindly help.

But I need sql date to use in my entity beanjava.sql.Date doesn't have a time component. java.sql.Timestamp does. If your bean has been written to use java.sql.Date then obviously it doesn't need the time component.
