Hi everyone, I have date variables in the following format - yyyymmdd_hhmmss

I've looked at the existing date variable conversion threads and can't find one that helps for this specific type of format. Here's examples of the strings in the variable

TIMESTAMP
20210219_193618
20210219_195936
20210220_143856
20210220_161023
20210221_154242
20210221_161101
20210221_172955
20210221_181902
20210221_185542
20210221_192824

As you can see the format has the year, month then day, followed by an underscore, then the hours, minutes and seconds.

How can I convert this to a date format? I've tried the following code -

Code:
generate voucher_date=clock(TIMESTAMP, "yyyymmdd_hhmmss")
and it produces missing values.
