TraceTime

TraceTime is an Obsidian plugin that tracks and displays the last edited time of every block (paragraph, heading, code block, list, table…) in your notes, with labels aligned to the right of the document area.

Features

• Block-level time tracking: incremental re-parsing via CodeMirror ChangeSets — only blocks near the edit are touched, never a full-document diff
• Undo/redo aware: restoring content with Ctrl+Z restores its original timestamp (content-hash session history)
• External change recovery: timestamps migrate by block hash when files are changed by sync tools or other editors
• Configurable display rules: a ladder of formats (just now → minutes ago → hours ago → today → yesterday → days ago → this year → full date) with a live-preview settings tab
• Timestamp rollback: every write keeps a one-generation backup; restore from the settings tab if timestamps ever get clobbered
• Performance first: millisecond incremental path, viewport-only rendering, debounced batched writes, no full-vault scan on startup

Data storage

Time data lives in <vault>/.obsidian/plugins/tracetime/records/, one MessagePack record per Markdown file. Note content is never stored — only block hashes, the first/last 32 normalized characters of each block, and timestamps.

TraceTime（中文）

TraceTime 是一个 Obsidian 插件：为笔记中的每个块（段落、标题、代码块、列表、表格……）记录并显示"最后编辑时间"，标签统一显示在文档区右侧。

特性

• 块级时间追踪：编辑时通过 CodeMirror ChangeSet 做增量窗口重解析，只处理改动附近的块，不做全文 diff
• 撤销/重做感知：Ctrl+Z 撤销后内容回到旧版本，时间戳一并恢复（基于内容哈希的会话历史栈）
• 外部修改恢复：同步软件或其他编辑器改动文件时，按块哈希回迁时间戳
• 可配置的显示规则：阶梯式规则（刚刚 → N 分钟前 → N 小时前 → 今天 → 昨天 → N 天前 → 今年 → 完整日期），设置页带实时预览
• 时间戳回滚：每次写入前自动保留上一代备份，误刷后可在设置页一键恢复
• 性能优先：毫秒级增量路径、视口内渲染、防抖批量落盘、启动不扫描全库

数据存储

时间数据保存在 <库>/.obsidian/plugins/tracetime/records/，每个 Markdown 文件一条 MessagePack 记录，不保存笔记正文（只存块哈希、前后各 32 个标准化字符和时间戳）。
