The naming scheme used is surely known to analog via the LOGFILE

Eg LOGFILE sys$disk:[]access_log_combined_%Y-%M-%D.gz;*

would be daily files, from midnight

But this is absolutely not typical. It's normal to rotate at 2am or 3am. Then this logfile covers some of the stated day and some of the previous day. So you'd have to include it if you wanted a report for either day.

Another common scheme is that logfiles are only rotated weekly, but named after the day on which they're rotated. So if you want any part of the preceding week, you have to read this logfile.

And don't get me started on timezones.

Analog simply has no way to know this stuff without built-in knowledge of the rotation schedule used, and of the naming of the logfiles when they cover a certain time span.
