Rounding time to nearest hourly quarter

I have several records like
2/19/2010 1:25:46.000000 PM
2/19/2010 1:40:46.000000 PM
2/19/2010 1:55:46.000000 PM
2/19/2010 2:10:46.000000 PM
I want to round them off to the nearest quarter like
2/19/2010 1:30:00.000000 PM
2/19/2010 1:45:00.000000 PM
2/19/2010 2:00:00.000000 PM
2/19/2010 2:15:00.000000 PM
Any ideas how I would do that? a trunc(col,'mi) only lets me round it to the minute..
Note that records are not necessarily in the 5 minute interval difference it can also be 7 minute difference or 4 minute difference from the nearest quarter...
so I can also have records like
SysUpTime     2/19/2010 10:31:00 PM
SysUpTime     2/19/2010 10:57:00 PM
SysUpTime     2/19/2010 11:31:00 PM
etc.

But OP asked for "*Rounding* time to nearest hourly quarter". Same applies to Aketi's solution which, BTW, which always bumps it up to next 5 min.In which case, just substitute "Round" for "Floor"!
Although thinking about it, you'd probably want to add seconds into the mix:
with table_x as (select to_timestamp('11/03/2010 11:45:39', 'dd/mm/yyyy hh24:mi:ss') t from dual union all

Rounding time field to nearest half hour

Post Author: fiscyn
CA Forum: Formula
Is there a way to round a time field?
For example, if a time field is from 9:01 to 9:14 I want it to round back to 9:00;
9:15 to 9:29 or 9:31 to 9:44   I want either option to round to 9:30
and 9:45 to 9:59 I want to round to 10:00.
I want to keep the original time and have the rounded time listed next to it.    Also I want this for a 24 hour clock, military time. Don't know if that makes a difference.
Any help is appreciated.
Thanks.

CA Forum: Formula
I'm slowly getting this to work.    Just a couple problems, minor I hope.
I used the CTime function and used the rounding formulas for minutes and hours as you suggested. It works great.   But the results for the hours come out as 12.00 and the minutes as 30.00 or 0.00.   How do I drop the decimals?   I tried the totext, 0 function, but the numbers don't line up correctly.   If the hour is 9.00, it drops the zero place holder.   So if 9 and 10 are lined up, the 9 is above the 1 instead of the 0.
It works fine for the minutes except I end up with 0 instead of 00.   Any suggestions?
I greatly appreciate the help so far.   Thank you.

Rounding minutes to nearest five.

Hi,
I have tried the various methods suggested on other forum messages but to no avail.
I have a GUI that acts as the client for a reminder system i am making for some coursework.
It contains a combo box with values for the user to select a time from, however the time is not displayed in the format i would like it to be.
I would like the current time from the instance of calendar i have created to be rounded to the nearest five up.
The code i have for the combo box at the moment is:
     cal.set(cal.MINUTE, (int)Math.round((double)cal.MINUTE));
          n=0;
          int z = 0;
          while(z<288)
               cal.add( cal.MINUTE, n);
               s = DateFormat.getTimeInstance(DateFormat.SHORT).format(cal.getTime());
               time_cb.addItem(s);
               n=5;
               z++;
This code always sets the first value of the combo box to 10 minutes past the hour and increments it by five from there. This happened with all the other methods i tried from the other forums also.
I would like it to round to the nearest five the current time and increment by five from this time.
Thanks for your time and help.

CATS Rounding up the Total Hours to next 1/10th hour.

Hi Everyone,
Is there any user exit or standard configuration which can be used to round up the total hours in CAT2 to the next 1/10th hour.
Eg : If the employee enters start time and End time as 08:00 and 08:06 then total hours is .1 ( 6/60 = .1)
But if the employee enters Start time and End time as 08:00 and 08:02 then the total hours should also give as .1 instead of .03 which is ( 2/60 = .03 ). That means it should round up to every next 6th Increment.
Kindly suggest,
Regards,
SAP HCM

you can round it in Time eval through PCR quering time pairs . ROUND operation can be helpful.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." Tried suggestions I've seen on the forum.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." I've tried various suggestions I've seen on the forum but nothing has worked. TIme Machine worked fine for the last two years and just suddenly started having this problem every time. The only thing that was a little different is that the computer was off for a week while on vacation and then I added a large amount (20 GB) of photos. Now the requested backup size is 82GB, which is large, and process proceeds very slowly for 2-3 hours before failing with the message mentioned. I have more than enough available backup storage space for it. Before failing, Time Machine has backed up no more than 12GB or so of the backup. It fails during different files each time.
I've turned off the computer sleep feature, and I've checked that the NAS is set to never automatically power down. I normally backup over Wi-Fi, but I've also tried connecting to Ethernet and it still has the same problem. It's odd because I also have a MacBook Pro that is still backing up fine to the same NAS using the MacBook's Time Machine.
I am using an iMac with OS X 10.6.8 and an Iomega StorCenter ix2-200 NAS.
I have system logs that I can share if helpful. The logged messages vary a bit from run to run, but here are some messages that I've been seeing:
I always get this message near the beginning of the backup:
Event store UUIDs don't match for volume: Macintosh HD
I've gotten this messsage a number of times:

That looks like a problem was found with the file system (data) on the TM disk. I don't know the details, but OSX tried to recover it from the journal, and found extra data on the drive. Likely a result of the incompatibility mentioned above.

Something caused a disconnect. Can't tell from the log what it was.
I doubt it's a problem with something in OSX being damaged or corrupted, but reinstalling OSX isn't a major hassle, so might be worth a try.
To be incompatible with Snow Leopard, this NAS must be at least a couple of years old. It may be beginning to fail.
Contact the maker. See if there's an update to make it compatible with Snow Leopard. If so, that might fix it.
If not, or if that doesn't fix it, see if they have any diagnostics that will shed any light.

MY new Ipod Nano does not hold a charge. I use it mostly as a watch, perhaps look at it 5 or 6 times in 8 hours, and leave it in sleep mode the rest of the time. I drains to the red line in less than 2 days. My husband's nano will last a week this way.

Am I doing something incorrectly to cause this short battery life?

You are still under warranty if your iPod is "new." Take full advantage of it by either calling iPod tech support, Apple Care if you have it or take it in to an Apple store or an AASP. Whichever is more convenient for you.

HT201250 If time machine backups hourly. Why does it need to backup daily, weekly and monthly

If time machine backups hourly. Then why does it need to backup daily, seekly, and monthly?

It doesn't.
What it does is discard intermediate backups at the end of 24 hrs and keep just three spaced backups from the previous day.
At the end of the next day, that day's will be reduced to 3, and the previous 3 trimmed to one; the last backup of that day.
Daily backups are kept for a month, then trimmed to the last backup of the week.
The weekly backups are kept until the disc runs out of space and TM starts deleting the oldest ones.

let me know what would be the reason that 1st million takes only 15 minuts and the time goes on increasing gradually with the increase of dataYes that's a little strange. I only can guess:
1. You are in archivelog mode and the Archiver is not able to archive the redo logs fast enough
2. You don't use Direct Load and DBWR ist not able to write the direty block to disk fast enough. You could create more DBWR processes in that case.
3. Make a snapshot of v$system_event:
create table begin as select * from v$system_event;After the import run
create table end as select * from v$system_event;Now compare the values:
select * from begin order by TIME_WAITED_MICRO descwith the values given you by
select * from end order by TIME_WAITED_MICRO descSo you can look where your DB spent so much time waiting for something.
Alternativly, you could start a 10046 trace on the loading session and use tkprof.

Rounding off to nearest whole number without condition

hi,
i want to round a real number to an integer value,,wihout any conditions like
10.01 should be 11
10.1 should be 11 and like that
is it posible to do it?
thanks in advance.
amit

It doesn't look like you are trying to round to the nearest whole number here. It looks like you are trying to find the smallest integer value that is greater than or equal to the real number. If so, you would want to use the CEIL function (i.e.
1 SELECT CEIL(10.01)
2* FROM dual
SCOTT @ hp92 Local> /
CEIL(10.01)

Timer shows incorrect hours on lock screen in iOS 7.0.4 (11B554a)

Majority of time, I only use timer to count down for 30 min or 45 min so I did not notice the problem.
However, when it came to 1 hour and 30 min, it displayed as 23:30:00 in the lock screen. Therefore I came back and checked again to make sure i did not slide to incorrect hour by mistake. I reset the time to 1 hour and 30 min but again it displayed as 23:30:00 in lock screen.
This time, I tried to do 23 hours and 30 min but it displayed as 21:30:00. Then, I tried 0 hours 30 min and it was normal 0:30:00. Also, I tried 3 hours and 30 min but again it displayed as 1:30:00, which was what i wanted but i was thinking what it displayed might not be the actual value it was counting down.
That's the question i wanted to leave to the expert to investigate.

Button can be clicked only 4 times within 24 hours?

I want to create a JSP page which has one button. Requirement of project is that button can be clicked only four times within 24 hours. After 24 hour it should again allow to click button for max four times. How can I do this? Please help.

Hi,
In our project we implemented the same functionality,
This can be simply achieved by object serialization.
i.e you can store object with two attribute say clickCount , startDate and endDate.
you should have seperate thread which does activate and deactivate operations on button with buttonactivateFlag.
when button is clicked you should check for flag and do accordingly, if active increment clickCount, else dont allow.
Thread part: thread update the endDate attribute in object by constant freqency, if startDate != endDate then next day.
buttonactivateFlag = true;
startDate = endDate = current date;
clickCount = 0;
I hope this will work fine!

To use Time-Series type calculations, I understand that I have to create an OLAP dimension of type 'TIME' (and not 'USER') and map it to the populated relational time dimension table.
1) Can I have the primary key for 'Hour' level as the actual base level value of datatype DATE (eg. 02-SEP-10 10:00:00 AM) ?
2) For the END_DATE and TIME_SPAN attributes at the 'Hour' level, what should I use?
The documentation is only available for minimum 'Day' level hierarchies, which allows setting END_DATE and TIME_SPAN to the actual 'Day' value and 1, respectively.
3) For the END_DATE and TIME_SPAN attributes at the 'Month' level, do I need to supply the last-date-of-each-month and number-of-days-in-that-month, respectively?
Please bear in mind that I am relatively new to Oracle OLAP. Any assistance will be appreciated.
Cheers.

Thank you Szilard and Adnan for the very prompt and informative responses.
I managed to follow the advice on the oracleolap.blogspot link and created a time dimension with members at Hour level loaded into the dimension in character format: TO_CHAR(hour_id, 'DD-MON-YYYY HH24')
The problem now is the maintenance (loading) of the dimension is taking an abnormally large amount of time (over 1 hour) as opposed to when the members were being loaded in DATE format (5 minutes). The mapping table only as 10,000 entries.
Why is these such a big difference? Is it normal? Is there a way to speed up the maintenance time?
FYI, I have not created any indexes on any of the attributes.
My platform is:
