On the other hand, if your "database" really is just a text file and you want to find the records that match a strict time string there's already a fast native utility for this available: grep (*nix) or findstr (Windows). The advantage being that you could search for more than just the time. It's still limited to only textual matches, not smart matches (e.g., ranges). In the end, a custom program will be more powerful to process the data. Alternatively, if the data is a text file and you want to query it regularly, consider learning a bit about SQL and sqlite3 and import the data into a "real" database first. Then you'll get the full expressive power of a query language and the performance improvements of binary data and indexing (if you tune it right).
