Is there some sort of trick (apart from saving a project and running a windows task to initiate it) within FME to set a clock as a tranformer to count to 1hour before starting the next transformer? I basically want a count time timer workbench transformer to wait 1 hour before starting the next one.

As a workaround, check your workspace for transformers that contain "Parallel Processing Level" options, and change those to "No Parallelism".
More information on FME's parallel processing.
You can use LineJoiner transformer with parameter List Name. But you need to do some additional data processing:
- Use
LengthCalculatorto calculate lengths. - Use
Sorterto sort your lines by length (numeric sort, descending). - Use
LineJoinerto join lines. The biggest ones first (thanks to step 2). Specify parameterList Nameof theLineJoiner- some name for new list attribute. - Use
ListIndexerwith list index 0 - to get the first joined feature (the biggest one) attributes' from the list.
Here is how it will look:
EDIT1:
In order to be able to join only <1m features to bigger ones we need additionally to use:
Testertransformer after LengthCalculator with test:_length < 1- Use
SpatialFilter(tests to perform parameter:TOUCHES) after Tester to filter only that features which touch features <1m. Then perform line joining on them together with <1m features. Features that don't touch <1m, direct to output (or further processing).
Model:
EDIT2:
If you have <1m line that touches two big ones then they all will be joined together. If such case (<1m feature touches two or more big ones) is possible in your data then you should add some processing of such cases. Take a look at parameters Merge Attributes and Attribute Prefix of transformer SpatialFilter. Using these parameters you should be able to detect such cases and then do some additional filtering.
EDIT3:
Let's solve the case when you have two big lines touching one small (<1m). We need to take only one of the big lines to participate in joining with small one.
In order to be able to perform such filtering we need to mark these two big features with some id from small one they are touching. As stated in EDIT2, it can be done in SpatialFilter transformer using parameters Merge Attributes and Attribute Prefix.
Then use transformer DuplicateRemover to filter such duplicate features (two big) and take only one of them.
Hint: try to use Inspector transformer during creating your model and view intermediate results in any case that is not clear to you. In such way you will better understand how each of the transformers are working. Experiment with your data! :)

There is a Decelerator Transformer, but I'm unsure of the maximum amount of time you can pause a function--it is measured out in seconds.
If you are using the .bat code created in fme, you could modify it to add a pause between workflows. Again, measured in seconds.
Pausing for an hour between transformers seems excessive--how many transformers do you have to iterate through?
