You can use this page to specify the log file information time range to be analyzed.

The program contains a built-in time range cache. The cache contains information on time ranges of previously analyzed log files. The program uses it to quickly determine if it is necessary to analyze a file when some time range is specified in the profile properties. The cache contains information on size and date of each cached file, so the program checks if a log file hasn't been changed and it is possible to use the cached time range without reanalyzing the file.
