EXTRACTING date time format from a data table


#1

Can anybody help me to extract date time format from a data table. Below is my data table.
I have tried sub string-but it isnt accurate as each time the data table for each pdf gets dynamic,
I came across regex, but through regex I am able to get all date time strings.

below is the sample data table, so i need to extract the date time for two cases(they are in bold)…so the data table might differ each time, but the details would definitely be there as in date time which i would want.
