klog – plain-text time tracking tool

klog is a command-line time tracking tool built around a human-readable plain-text file format. Rather than storing work records in a proprietary database, it keeps the underlying information easy to inspect, edit, version, search and process with ordinary text-oriented tools.

The format supports dated records containing durations, clock-based time ranges, summaries and tags. klog then provides commands for evaluating these records, producing totals and reports, filtering data and converting it into forms suitable for further processing.

This is free and open source software.

Key Features

  • Human-readable plain-text format designed specifically for time tracking.
  • Record durations directly or use start and end times.
  • Supports open-ended time ranges for work that is still in progress.
  • Add free-form summaries and tags to time entries.
  • Calculate totals across one or more klog files.
  • Generate reports from recorded working time.
  • Filter records by dates, periods and tags.
  • Generic filter expressions support logical AND, OR and NOT operators.
  • Group filter expressions with parentheses and arbitrary nesting.
  • Filter over custom date ranges including quarters and other periods.
  • Fill gaps when producing reports for specified time periods.
  • Compare recorded totals with expected totals.
  • Print records with per-entry and aggregate durations.
  • JSON output makes recorded data available to scripts and other programs.
  • Validation and warning facilities help identify problematic or unusual records.
  • The plain-text approach works well with version control, editors and standard Unix text processing tools.
  • Native Linux builds are available for 64-bit AMD and ARM systems.
