The TimeDiff plugin is a useful tool for tracking time intervals in your Obsidian notes. With this plugin, you can create a "timediff" markdown block to calculate and display the differences between various dates and times. The plugin also provides three commands: one to show the total time difference count in the current file, another to insert a timediff block at the cursor position, and a third to insert the current time at the cursor position. This plugin is ideal for anyone who needs to track time intervals or create schedules in their notes, and it can be a valuable addition to your Obsidian workflow.
