I want to see which users are logging into Retain since a specified time. How can I do that?

You can do that with a SQL query. This example will be for MySQL, but the same concept applies for MS SQL or Oracle. For example, MS SQL uses "dbo" before the table name whereas MySQL does not.
To see all users that have ever logged in:
SELECT * FROM retain.t_user WHERE ts_lastlogin > 0;
To set a timeframe, for example since January 1, 2015, you first have to convert that date into Unix time, because the date/time of the login is stored in Unix time in the database. Unix time is the number of seconds that have transpired since January 1, 1970. It is commonly used in programming.
Then, run this query:
SELECT * FROM retain.t_user WHERE ts_lastlogin > 1420092000;
Note that, for this example, 1420092000 is January 1, 2015 at the top of the hour (00:00) Mountain Daylight Time (GMT -6). That string will be different for other timezones.
You can send the query to a CSV file:
SELECT * FROM retain.t_user WHERE ts_lastlogin > 1420092000 INTO OUTFILE '/[path and filename]' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n';
