I’m loading data into a MySQL table with PHP using LOAD DATA LOCAL INFILE. There are date fields in the import file that are in the format 10/11/2021 02:49 PM America/New York. How do I deal with the time zone text at the end? I have tried stripping it off, but can’t get it to work. The date comes in as 0000-00-00 00:00:00 every time.

Variations I have tried….

SET revision_date = STR_TO_DATE(LEFT(@revision_date, 19), '%m/%d/%Y %h:%i:%s %A'),
SET revision_date = STR_TO_DATE(SUBSTR(@revision_date, 0, 19), '%m/%d/%Y %h:%i:%s %A'),
SET revision_date = STR_TO_DATE(SUBSTR(@revision_date, 0, -17), '%m/%d/%Y %h:%i:%s %A'),

The only thing I’ve been able to get to work is stripping the time zone off in the csv file before importing and using…

SET revision_date = STR_TO_DATE(@revision_date, '%m/%d/%Y %h:%i:%s %A'),

New data will be loaded frequently, and there are several thousand line of data in the CSV file, times three date fields, so I really would like to deal with it on the import if possible.

Method 1

The sample date you have given is using a 12-hour clock with AM/PM. For that specific date you can use

SET revision_date = str_to_date('10/11/2021 02:49 PM America/New York','%m/%d/%Y %h:%i %p');

which returns 2021-10-11 14:49:00

Note %p, not %A for the AM/PM indicator.

I’m assuming all dates are in the same format (no mixed 12-hour and 24-hour clock or US/European date formats), and that you’re familiar with LOAD DATA INFILE syntax.

Method 2

Answering the question with my solution for future reference. Date data was loaded into table as is, into a VARCHAR() field. Then re-formatted into a date format by stripping off the time zone text, when the table was queried for that field.

$revision_date = date('Y-m-d H:i:s', strtotime(substr($revision_date, 0, 19)));
