Compute the last 24 hrs from current time

Hi
Given the current time as "20021017 16:00:00 GMT", how can I compute the previous 24 hours. The result will be strings "20021016 16:00:00 GMT" and "20021017 15:59:59 GMT"
Thanks

How about this?
Calendar cal = Calendar.getInstance();
cal.add(Calendar.HOUR, -24);Regards,

HT1386 I am unable to synch photo albums from ipad 3 to itunes on my windows pc. In addition to camera roll and ipod cache albums, i have 6 other albums made from pix derived from the camera roll. I have trawled the net for the last 8 hrs in vain!

Dear Community members,
I am unable to synch photo albums from iPad 3 to iTunes on my Windows 7 pc.
In addition to Camera roll and iPod cache default albums, I have 6 other albums made from pix derived from the camera roll. Eg - Family pix in a folder, Office pix in another, Plant pixs in another, House architecture pix in another.......all also exist in the camera roll.
I have trawled the net for the last 8 hrs in vain!
I have ios5 on Ipad 3 and the latest Itunes on Windows PC.
As a precaution, I have used the windows "add pictures from...." to keep a copy in a separate folder in the windows desktop, but again it has all the pics mixed up together and not sorted as per the various albums in the ipad!
How to replicate the albums in the windows PC???
Regards

Sync the photos back to the iPad using iTunes. You have to place the photos into a folder from which you sync photos. All photos that you want to sync to the device must be included in the main photos folder and selected to sync each time that you sync.
Connect the iPad to the PC and launch iTunes.
Click on the iPad name on the left side under devices.
Click on the Photos Tab on the right.
Click on the Sync Photos From heading in order to select it.
Select the photos folder that you want to sync from.
Select all of the albums or photos within the folder that you want to sync.
Click on Apply in the lower right corner of iTunes

Help find the Last run date from previous month

Hi all
I am stuck trying to find the Last Run Date from the previous month.
select distinct(date_ran) from TABLE X where date_ran like '%/11-%' order by date_ran desc gives
"03/30/11-06:19
"03/25/11-03:01
"03/24/11-03:00
"03/23/11-03:00
"03/22/11-03:00
"03/21/11-03:00
"03/18/11-03:00
"03/17/11-00:00
"03/16/11-06:31
"02/15/11-07:42
"02/15/11-06:00
"02/14/11-08:19
Here the result I am trying to acheive is 02/15/11-07:42 ;Note the column date_ran is a VARCHAR2(255) and not a TIMESTAMP
I tried
select ADD_MONTHS(to_date(max(date_ran), 'MM/DD/YYYY-HH24:MI'),-1)
from daily_tests_a
where date_ran like '%/11-%'
order by date_ran desc
which returns 2/28/0011 6:19:00 AM and that is not the result I am looking for

Points in time should always be stored in DATE (or maybe TIMESTAMP) columns. If not, you're going to waste resources converting them to DATEs whenever you need them to behave like DATEs, and risk run-time errors because of bad data.
Normally, the "previous" month means the month before the current month. In April, the previous month is March.
By "previous" month, do you mean the 2nd latest month in the table? That is, this data contains data from February and March, 2011; March 2011 is the latest of those months, February 2011 is the next-to-last, and so is that why you want a date from February?
I tried
select ADD_MONTHS(to_date(max(date_ran), 'MM/DD/YYYY-HH24:MI'),-1)
from daily_tests_a
where date_ran like '%/11-%'

SMKTry this:
WITH got_real_date AS
 SELECT TO_DATE ( SUBSTR (date_ran, 1, 14)
 , 'MM/DD/RR-HH24:MI'
 ) AS real_date
 FROM table_x
-- WHERE ... -- If you need any filtering, put it here
SELECT TO_CHAR ( MAX (real_date)
 , 'MM/DD/RR-HH24:MI'
 ) AS last_date
FROM got_month_num
WHERE real_date < (
 SELECT TRUNC (MAX (real_date), 'MONTH')
 FROM got_real_date

I'm trying to set up a DAQ assist just to measure some voltage, how do i get the graph to start from 0 (time) every time I press run

Hi all,
I am trying to set up a simple DAQ assist to measure some voltages (currently a 9 volt battery to aid set up), when choosing to use a waveform chart to log the voltages the graph doesnt start from 0 (time seconds) how do I do this and get it to reset every time I press run or even stop.
What I want to see at the end is a chart for the full lenght of the test showing voltage against time in seconds.
Any ideas peeps
many thanks
Shane

Hi Shane,
Look at this VI
Here, I clear the chart before running the VI, using a 'history data' property node ( i pass an empty array to clear it)
In effect, each time you run the VI, the chart will begin at 0:00
Hope this helps
Regards

I'll ask this again. I'm running Yosemite, LR 4.4 everything was running fine and I'm not sure if this is connected but when I loaded the last security update from Apple I started getting the "no content" box when I tried to publish to LR (Facebook OK),

I'll ask this again. I'm running Yosemite, LR 4.4 everything was running fine and I'm not sure if this is connected but when I loaded the last security update from Apple I started getting the "no content" box when I tried to publish to Flickr (Facebook OK), now I can't get it to authorize, I loaded 3rd party JR plug in and still get can't authorize. Can anybody help? Basically LR is useless, it has been nothing but problems.

It would probably be better to continue your previous thread on the same question than to start a new one.

Go to the above website, sign in to your AppleID using the "Manage your Apple ID" link, and make sure everything is correct. If it is, then clearly, at the least, the emails are in error.

I was trying to change from my iphone 4 to my new iphone 5, and i backed up my contacts onto iclould, when i restored my iphone 5 on my computer, the contacts were wiped from both devices, how do i recover the contacts?

i was trying to change from my iphone 4 to my new iphone 5, and i backed up my contacts onto iclould, when i restored my iphone 5 on my computer, the contacts were wiped from both devices, how do i recover the contacts?

On the iPhone tap Settings > iCloud
Make sure Contacts is switched ON. It may take a few minutes for the data to sync via Wi-Fi.
If you are using iCloud, there's no need to connect your iPhone to a computer via iTunes to sync your contacts.
