I'm getting closer. Now my only problem is the time field is displaying in 24h instead of 12h. Any ideas?;

SELECT

x.CounterDateTime, -- stare & compare

[Date] = CONVERT(VARCHAR,x.CounterDateTime,101),

[Time] = RIGHT(CONVERT(VARCHAR,x.CounterDateTime,0),7)

FROM (-- "Native" CounterDateTime looks similar to this

SELECT CounterDateTime = '2013-12-30 12:09:00.123' + CHAR(10)) d

CROSS APPLY (-- so convert it to a date and work from there

SELECT CounterDateTime = CAST(CAST(d.CounterDateTime AS CHAR(23)) AS DATETIME)) x

I give up. Even if I manage to display it correctly, it's not treating the field as a timestamp so ordering gets all messed up.

Figures a Microsoft logging application would make it extremely difficult to work with another microsoft product

I'm getting the data from Microsoft Performance Monitor. The date field is not a date field

If I sort the data after cast/convert, 12AM comes after 11AM instead of before 1AM. Neither SSMS or Excel is treating the field as a date.

Should be

12:00AM

01:00AM

02:00AM

instead of

01:00AM

02:00AM

...

11:00AM

12:00AM

I know where you're getting the data from which is why I specified this above:

SELECT CounterDateTime = CAST(CAST(CounterDateTime AS CHAR(23)) AS DATETIME)

FROM (SELECT CounterDateTime = '2013-12-30 12:09:00.123' + CHAR(10)) d

-- 2013-12-30 12:09:00.123

which converts the wacky MS string-thing to a datetime, allowing you to use CONVERT or whatever to get the bits you want in the format you want. But what's consuming this data? Is it the data source for a report, for instance?

Yes it's a data source for an Excel Pivot Chart. I'm trying to show a timeline of certain server performance metrics.

This allowed me to format the date how I would like;

CONVERT(CHAR,CAST(CAST(CounterDateTime AS CHAR(10)) AS DATETIME),101) AS Date

I can't post my time code because the forum won't load and keeps timing out. It might be the firewall at work detecting something... No idea

The time code I settled on allowed me to sort it and show AM/PM but it is in 24h format instead of 12h. Not a huge deal but it's all I need to be 100% satisfied with the report.

That will give you date but not time. The code I posted returns datetime, from which you can extract both date and time

CAST(CAST(CounterDateTime AS CHAR(23)) AS DATETIME)

and it's intuitive too - the standard datetime as string ['2013-12-30 12:09:00.123'] is 23 characters.
