Parsing the following sourcetype for a custom field extraction on a single field, why is only "Nov" extracted instead of the full date?

When parsing the following sourcetype, the field Example1 results in "Nov" instead of the full date. The rest of the fields are extracted properly. I'm wondering, is there anything specific I need to add to props/transforms for this? Nov 2 2015 11:06:00:200AM , Example1=Nov 2 2015 11:06:00:260AM , Example2=ALONGNUMBER, Example3=7 , Example4=7 , Example5=STANDARD, Example6=AGuestAccount , Example7=SomeCommand, Example8=example-server, Example9=5992, Example10=60
