Variable date/time format with am/pm

I am attempting to read-in the following date/times, where the day and month can be either a single or double digit, and have looked through a number of related threads without arriving at a solution.

1/1/2017 12:00:00 AM
1/1/2017 5:00:00 AM
11/15/2017 10:00:00 AM

In 3.235 “String to date” node I’ve tried;

*d/*M/yyyy *h:mm:ss aa (and with just a)
dd/MM/yyyy hh:mm:ss aa (and with just a)
d/M/yyyy h:mm:ss aa (and with just a)

I am in Wildcard mode for the first one, of course, though I cannot get a Match to Include, it stays stuck in Mismatch Exclude.

I was successful using this node on a different data source that was 24hr time and had a single format for datetime (e.g., 01/02/2017 01:00:00)

Am I using the right date conversion node for this datetime input format?

@WilliamStewart welcome to the KNIME forum. Di you have a look at this example and the linked discussions?

I had already looked at the linked solution by you, which does not appear to solve my problem. I don’t understand what is going on in the diagram in the link you provided above as I can’t see how the nodes are configured.

Here’s what my workflow looks like right now, with some experimenting.

@WilliamStewart You can actually download the workflow and see the configuration for yourself. In the example there is an if then condition in the Rule Engine node.

Ok, that resolved the matter. I thought I had to build a reg expression in the upper area, and that the entry area in the lower area was only a picklist. Now I see it’s a combo.

Thanks!

Glad it did work. If you want to further explore the possibilities and quirks of date and time variables I have a small collection of example workflows.
