I was little too hasty since there was no proper sample data.
This, however, finally sorted things out. Base date is incredibly Dec 21, 1899.declare @twit table (num1 int, num2 int, dt1 smalldatetime, dt2 smalldatetime)
insert @twit
select 55638330.0, 55638390.0, '10/3/2005 16:00:00', '10/3/2005 15:45:00' union all
select 55638225.0, 55638240.0, '10/3/2005 18:30:00', '10/3/2005 17:30:00' union all
select 55638495.0, 55638510.0, '10/3/2005 20:30:00', '10/3/2005 20:15:00' union all
select 55638120.0, 55638660.0, '10/3/2005 23:00:00', '10/3/2005 14:00:00' union all
select 55638120.0, 55638660.0, '10/3/2005 23:00:00', '10/3/2005 14:00:00' union all
select 55639770.0, 55639830.0, '10/4/2005 16:00:00', '10/4/2005 15:45:00' union all
select 55639665.0, 55639680.0, '10/4/2005 18:30:00', '10/4/2005 17:30:00' union all
select 55639935.0, 55639950.0, '10/4/2005 20:30:00', '10/4/2005 20:15:00'
select *,
case when num2 - num1 = datediff(minute, dt2, dt1) then 'proper sample data' else 'sigh...' end,
dateadd(minute, num2, -11) as newdt1,
dateadd(minute, num1, '18991221') as newdt2
from @twit If you look at the pair of records that are not proper sample data, you can see that you get exactly the wanted result when shifting them.

I bet the base date was the real answer he was looking for, that's why he never answered the question of what is 55638330?

Actually if you are going to be such a jerk Peso, No I dont want your help. As for sloppy work, you got the point. How many examples did you need, you know what i was trying to accomplish. All I did is copy and paste. It is difficult to lines things up in this editor.
Thanks,
James Bosco |

Hey! Welcome back! What brought you back after almost 2 weeks from last time?
1) All I needed was one proper sample data.
2) No, I had no idea what you were trying to accomplish. I had to do all the research myself.
But you are welcome with your excellent feedback.
You are right about I'm not being your personal tutor. The question remains if anyone else will.

James -- why don't you go back and re-read your questions and the responses. No one is concerned about the *formatting* of your sample data, it is that it was NOT ACCURATE and did not help us to understand what you are looking for, and you NEVER specified what you need precisely and accurately. Look at Peso's post at the very top of the second page, he used your exact data and it is not accurate -- how can this help us to find a solution for you??
Peso spent a lot of time using trial and error to guess what you needed, a lot of time that was unnecessary and he certainly isn't being paid for. Or, in your case, even thanked for ...
What if I ask you a very simple question:
"Please help me fix these numbers! I have
1
2
3
4
and I would like them to be like this:
3
4
7
Thanks!"
would you have any idea what I am asking for? Do you know what I need? It is very simple what I am after, very basic, but if I don't explain what I need and/or provide clear, accurate sample data and results, it is impossible to know what I am looking for!
Does this make sense?

Heck, I just wanted to know what the units were. JBosco says he told me five times, but he must not be using base 10, because I only count 0 times.
Jim
P.S. There are only 10 types of people in the world, those that understand binary numbers and those that don't! |

No I dont know everything. I never said I did. That is why I came here in the first place. Sorry to waist your time. I came here to ask a question and all I got was capped on when I did not give you exactly what you asked for. I never said I was perfect. I am sorry I am not as inteligent as you all seem to be. Dont worry I will not come here and aske any more questions. Sorry, I thought this was a forum for people learning as well as know allot.
Thanks,
James Bosco |

Capped? No one here at SQLTeam nor in this thread assumes you know everything.
Here are some very clever people willing to assist you as long as you help us.
All we did was ask you to give us PROPER sample data. Many times as I recall.
We asked nice and polite.
You know, all a date really is, is an offset to a certain point in time! So if you give us a number 13446576 we have absolutely no idea of what that is. No matter if you also give us the calendar interpretation of that number.
How shall we interpret that? Number of minutes passed since a certain fixed base date? Number of hours?
You tell us! But you didn't, even if we asked you to.
Here is the point were people started to loose interest in your problem. Because of you!
We don't have to help you. But we do, because we like to help and educate people like you to excel and learn.
BUT..! If you had given us another reference point, 14579466, and the calendar interpretation that is supposed to represent, it is very easy to calculate the differences in numbers and compare them with the differences in calendar representations. Now we can compare the time interval between them!
But in your case, there sometimes (about 50% of the sample data) was a difference of 3 hours between the numbers and the calendar representations, because of you not being tidy when posting them. It has absolutely nothing to do with formatting! Please understand this.
And that's why it took much longer time than usual to solve this case.
It seems that a large step in your learning process is to comply when asked to give some proper sample data, and you being willing to provide the material we need to help you.
Stop excuse yourself.
Until you overcome your issues, you will have same problems in the future.
Good luck.

Ummmmmmm
Why Not?
Maybe that's a good place to start.
If you don't understand what's being asked of you, maybe you should ask questions about that first.
All these guys are doing is trying to help you, help them
Pretty simple
Oh, and look at the hint link in my sig below....AND Read it
