Preserving date in time calculations in Numbers

I've scoured the discussion forums and I'm stuck on this one.
When I enter a time in a cell (e.g., '3:00 PM' in A1) and do a calculation using TIME and TIMEVALUE which results in a value in B2, I noticed that the date changes. Without explicitly saying so, the date in A1 defaults to today's date. After doing the calculation, the date in B2 ends up as January 1, 1904. Any idea how the date can be retained, or, even better, completely ignored? The root problem is that when doing conditional formatting on a time value, the date is also taken into consideration. If the date is ignored, my time calcuations would be correct. Since the date is not ignored, my calculations are thrown off by the date constantly being changed back to 1/1/1904.
What I have done as a work around is to enter the original time as '=TIME(5,44,0)', which defaults the date to 1/1/1904. But, it would be nice if I could just enter '5:44:00' and not have to worry about the date component.
Alternately, if the date can be retained in the TIME and TIMEVALUE calculations, it would also solve my problem.

Jinxed,
I'm not completely clear on your equations, based on your description. It would be better if you would quote your expressions exactly so we could examine them.
If you have a Date/Time value in A and write =TIMEVALUE (A) in B, there will be no date present in B whatsoever, so it won't change. You can still get it from A if you need it and B will contain the fraction of a day represented by the time of day in A.

Need help with date and time calculations please

Hello there.. Im stuck, and im hoping someone can help..
Working on a list to manage and track PTO. User completes PTO request form,
Fields
Name
Start Date (with time)
End Date (with time)
Total Number of Days/hours requested: (calculation)
Full Day: (Yes/No)
ok business need
user has the ability to request a certain number of hours as opposed to a full day.
After searching around on google. I found this calculation to help me figure out how many BUSINESS days being requested.
=IF(ISERROR(DATEDIF([Start Date],[End Date],"d")),"",(DATEDIF([Start Date],[End Date],"d"))+1-INT(DATEDIF([Start Date],[End Date],"d")/7)*2-IF((WEEKDAY([End Date])-WEEKDAY([Start Date]))<0,2,0)-IF(OR(AND(WEEKDAY([End
Date])=7,WEEKDAY([Start Date])=7),AND(WEEKDAY([End Date])=1,WEEKDAY([Start Date])=1)),1,0)-IF(AND(WEEKDAY([Start Date])=1,(WEEKDAY([End Date])-WEEKDAY([Start Date]))>0),1,0)-IF(AND(NOT(WEEKDAY([Start Date])=7),WEEKDAY([End Date])=7),1,0))
This works great as long as its a [Full Day]="YES", displays results in column labeled Number of days
now if [Full Day]="No", displays results in column labeled Number of Hours
BUT this is my issue (well part of it) it calcuate the correct number of hours.. but puts a "1" in "Number of Days" why.. dates have not changed.. I think Its something with the above calculation but I could be way off.
the end result is I need number of days to concat with number of hours
i.e 1 full day 4 hours 1.4
0 full day 5 hours 0.5
1 full day 0 hours 1.0
so that the total can be deducted via workflow.. from the remaining balance in a tracker. (seperate list)
Any angels out there??

Date and Time calculation in the Service Module

Dear all,
I have quite of a challenge here and i need serious guidance from your side.
My client is in services industry and requires to calculate the date and time when the service call as to be closed. Not only it depends on the contract type the service is linked to but as well on the priority.
The priority in Business One is unique, therefore we created a UDT (User Defined Table) to store the different 'response time' per contract/per priority. Example: a Platinum contract is always 24/7. But a gold contract priority 1 has to be closed in 240 minutes (4 workable hours) while a gold contract priority 2 has to be closed in 480 minutes (8 workable hours).
I created 7 user defined fields on the Service Contract header that calculates the workable minutes per day. So if my coverage for Monday is from 8 AM to 4 PM, my UDF called DiffMon will show 480. For Tuesday, they start a bit later, and the coverage is 8:30 untill 16:00, therefore my UDF called DiffTue = 450.If the check box before the day in the Service Contract window is not ticked, then the UDF shows zero.
I succeeded to calculate the expected closing time by using CASE WHEN statements as following, (all calculated in minutes):
     First, I need to check which day the Service call is created: A Monday or Thursday or... since my time coverage can change every day! I use SET DATEFIRST = 1 and compare today's date accordingly with my UDF DiffMon, DiffTue, etc.
     Then, When end of coverage time today Monday (4PM) minus the create time on the Service Call (1PM) is less then the time stored in my user defined table for that contract and that priority (i.e.480), then just add that to the create time and the create date (DateAdd(mi,...,...) ).
    When end of coverage time Monday (4PM) - Create time (1PM) + DiffTue(450) is bigger than 480, then I know I have enough time to solve my service call tomorrow Tuesday and I take the start time of Tuesday (8:30) + remaining time from yesterday (480-180 -> 180 = 3hours from 1PM to 4PM) and add that to the Create date + 1 so the end result will show Tuesday date and a time of 13:30
   Etc. untill I cover all possibilities based on which day is the service call created.
NOW, I need to include the holiday table !!!!!!!!!! And I can't foresee how the hell I am going to do that.
The maximum coverage can go up to 60 hours, that means more than a working week! What happens if I have more than one bank holiday in that week period? What happens when my holiday table tells me that date is a bank holiday but it is actually a Sunday and my contract is only running from Monday to Friday?
Am I going straight to a big mess up?
I will highly appreciate your comments,
Regards,
Frederic

Hi,
it is possible in query designer,
u do the two things for getting the days between to dates
1) in CMOD write the code for sy-datum create a customer exit variable in query as on caldate like eg zcedate
when 'zcedate'.
clear l_s_range.
l_s_range-sign = 'i'.
l_s_range-opt = 'eq'.
l_s_range-low = sy-datum.
append l_s_range to e_t_range.
u write this code exit_saplrrso_001.
it givs the sydatum
2) then u create one more variable on zdate limit with replacement path
then u go forto create the formula variable then it display ascreen there u select both customer exit variable and replacement path variable
zcedate-replacementpathvariable
it gives days i worked on this and succedded.
like the same way fortime also u can do but here at the time of creating the customer exit varible u go for option as range here
l_s_range-low = '20012009'
l_s_range-high = '29012009'
l_s_range-sign ='i'.
l_s_range-opt = 'bt'.
please try with the above one.

Hi All,
I want to calculate the number of days and the time by subtracting from two dates and time.

Removing the date and time formatting in Numbers '09

I'm inputting the number 65-06-19 into a cell and its automatically replaced by a date, if i try to remove the date it puts a time in its place and i want neither.
I know there must be a simple solution but i can't figure it out ...help!

Bhenny,
The simple solution is to Format the entire data range for this item as Text before you start entering data.
The more difficult one would be to figure out which Date format is causing the problem and eliminate it. I don't recommend that because if it isn't this particular piece of data, it's likely another one sometime in the future will cause a problem with one of the other formats. Better to treat it the simple way.

Date and Time Calculation

Dear all.
I need a function that receives a Date / Time and another Date and calculates the the sum of those values.
Best Regards,
Thanks In advanced.

Hai Rodrigues,
The function module CALCULATE_DATE also adds/subtracts days and months to/from a date. The following website also demonstrates a number of ways to add days/months taking into account working and non working days if that is any use. http://www.sapdevelopment.co.uk/tips/date/datehome.htm
CALL FUNCTION 'CALCULATE_DATE'
EXPORTING
DAYS = '0'
months = '01'
start_date = p_date
IMPORTING
result_date = p_date.
You can even check this function modules, it works fine.
Function Module Name:: ADD_TIME_TO_DATE
Short Description :: Adds months/days/years to date.
Entering a negative value will subtract from the date.
Parameters ::
Exporting:
I_IDATE : Initial date
I_TIME : Quantity to add
I_IPRKZ : Unit of time(D:day, M:month, W:week, Y:year)
Importing:
O_IDATE : OUTPUT DATE

Insert Date and Time doesn't update

i am inserting a date and time in my numbers documents so that i know which paper copy is the most current. i do this by going to Insert pulldown and selecting Data and Time while in a Footer Cell.
this data does not update upon re-opening the file and i end up printing multiple copies over weeks and months with simply the date that I inserted the Date and Time into the footer.
is there a way to do this so that it updates?
TIA

As most of the times,
this kind of question is answered in Numbers User Guide.
When you insert a date_time value in a cell, you insert a fixed value.
If you want a living one, you must insert a formula.
=NOW()
or
=TODAY()
would achieve your goal.

DVD camcorder (VIDEO_TS) - preserve clip date and time

I had asked this question on the forums a long time ago but iMovie did not seem to be supporting it reliably at the time. But since some time has passed, I wanted to check if iMovie '09 can import clips from a mini DVD (those used in camcorders to capture video directly on to DVD media) AND preserve the clip's date and time.
What I see is that the first clip gets some date and time related to the event's date and time (perhaps the start time of the first clip?) but all the other clips which are imported, get timestamps of 1 second after that first clip's timestamp.
These are all my home videos and in order to keep each clip short, I have had the habit of pausing after about a minute or two, resulting in MANY clips over MANY DVD's, so manually updating date and time is absolutely the last resort.
The DVD player can see the clip date and time correctly, and so could the camcorder (I have since sold the darn thing!) so I know that information exists somewhere in the DVD, but it seems like iMovie is unable to "see" it.
Any help would be appreciated, including programmability hints.

Thank you for your post. I figured out why iMovie was assigning today's date to everything that I imported. It turns out that many of my video files did not have a real "created" date--some had no date at all and some had Wednesday, December, 1967 or 9 (I think). iMovie defaulted today's date in both of these situations. I took your advice and ot A Better Finder Attribute and easily converted all of the files using the option to copy the "modified date" into the "created date" attribute. Now everything imports correctly into iMovie.

How to enter a new Date and Time each day in a Numbers Spreadsheet...

Hi... I have finally decided to move away from Excel and really give Numbers a shot... I have an application where each day I first enter the current date and time into a particular cell of a new row and then I enter some data in cells adjacent (in the same row) as that entered date-time. Then the next day I want to again enter the (new) current date and time and add more data next to that new date-time and so forth day after day... You can't use something as simple as =NOW() because then everyday, ALL of the date-times would change to the current time... Nope, now what I want... I just want to be able to EASILY and QUICKLY enter the current date-time value in one call and then have that specific value stay there forever... In Excel, this is accomplished with the keyboard shortcuts of
<cntl> followed by a semicolon (;) for the date
then enter a single space (for separation of date versus time) followed last by
<command> followed again by a semicolon...
So all together that is,
<cntl><;><sp><command><;>
and that puts something like
4/10/2010 9:49:00 AM
in a single cell...
That's what I now want to be able to do in Numbers...
How do I do that??? Do I use the menubar item "Insert Date and Time" and if so, how exactly do I get the current time to show up in the chosen cell??? With formatting??? Is there a keyboard shortcut method like the one I mentioned that works for Excel?? I've perused the manual and though I found lots on date-time, I didn't see how to do specifically what I want to do... I likely just missed it as surely it must be easy to do...
Any feedback would be much appreciated... thanks... bob...

In Numbers, how do I lock in the date and time data when an IF/THEN formula is used with the "NOW" function?

In Numbers, how do I lock in the date and time data when an IF/THEN formula is used with the "NOW" function?
=IF(I127,NOW()," ")
I127 equals a check box. The formula retuns a value of the current date and time when a check is placed in the box. How does one lock that date and time so that it cannot be changed?

I don't think it is possible to lock in the date and time using a formula. You could put NOW() in a cell, copy, and Edit Paste Formula Results where you want the result.
Or if you are "time stamping" a lot, you may find this Automator Service (Dropbox download) helpful. It puts a "Today" function (actually it should be named "Now" because it includes both date and time) in your Services menu like this:
Just doubleclick the .workflow package to install it. You may have to click "download anyway" in System Preferences > Privacy & Security.
If you want you can assign the service a keyboard shortcut in System Preferences here:

Date and time diffrence calculations

Dear Experts,
I have a doubt regarding the date and time diffrence calculation please help me out.
This is regarding the report called u201CVehicle tracking systemu201D. The purpose of this report is to give the user information like how many vehicles have come in and how much time each vehicle has parked in the filling in the refinery and also the average time taken for a customer.
For this we have created 4 info objects called
1)     Park In Time
2)     Park In Date
3)     Gate Out Time
4)     Gate Out Date
We have created a routine which calculate the difference in Vehicle Park In Date & Time to Gate Out Time and Date
The Time difference is number format.
Example: For Vehicle1
Park in Date and Park in Time are         27.11.2008 and 17:43:35
Gate out Date and Gate out Time are     29.11.2008 and 09:36:16
Here routine will calculate the difference in the above date and time and the output is like this     1,155.138,000 (i.e. 1day, 15 hours 51 mins and 38 seconds) that means the vehicle has parked for 1 day and 15 hours etc.
But we require the output like    1 day, 15:51:38
Please give us the solution how to go about it.
Thanks in advance,
venkat

Hi,
I think in regard to your problem, the solution will be to make the variables in the query runtime by the replacement path variable.
Please find the below link, its very much self explanatory and in regard to your problem.

How to automatically update date and time on Numbers spreadsheet

Would like to have printed version of Numbers spreadsheet reflect present date and time. I know how to do this in Excel, but can't figure out how to get there in Numbers.

Add the date and time to the Header or Footer in the Print Dialog via the Insert menu.
It is only semi-automatic, in that to update the date and time, you must either delete and reinsert the date and time, or you must open the token and update by clicking the Set to Today button.

In the numbers app, using the "date and time" function, is it possible to remove the time? I need to put together a list of dates, but I don't need or want times.

When formatting your column to date/time, pick Date & time, and then pick the letter i in the circle to the right. Then scroll down and pick "No time"
