Extract Unique points from table column and sort by smallest to largest for IndexMatch use

I have a spreadsheet that pulls in date from a table with date/time corresponding to a number. I need to be able to pull out all dates and times that are unique, sort them by smallest to largest.

Currently I am using

=INDEX(Table_ExternalData_1[SampleDateTime],MATCH(0,INDEX(COUNTIF($E$2:E3,Table_ExternalData_1[SampleDateTime]),0,0),0))

to extract from the External Data Table for unique values, but the values extract as they are found in the table. The makeup of the data is such that every 10-15 data points correspond to a unique tracked component, so the dates will never automatically be in the correct sequence.

The current attempt I am trying to make is to
1. import the data from an external data source.
2. extract all unique date and times.
3. sort the date/time by smallest to largest on separate sheet.
4. sort component values by date time into columns using Index/Match.

I am running into a problem getting 3 to work with a changing dataset. I think I am missing something simple, and I apologize if I am.

The test spreadsheet is attached to the post.

Thank you for the help.

I am not sure that it is going to do what I need to do. The way the table will be after I am done is that each component will be separated into columns, and placed with the rows being the applicable date/times.

Is this possible with a pivot table? I have attempted to use them in the past for my needs with this specific type of data sorting, but I never seem to be able to succeed.

The attached sheet has an example after the pivot table.

I have a png of the table example, and attached a renamed example as well.

Found a solution.

Utilizing a single row Pivot table, the data sorted the way I needed it to by entering only the data/times into the table. I was then able to use Index/Match to sort the data to the applicable rows.

Thank you for your help! It is appreciated.
