Timezone, dates, cron, timestamps for AI agents
Overview
A local MCP server that gives an assistant date, timezone, cron, timestamp, and duration calculation tools.
- What you can do
- Provides timezone conversion, timezone listing, current time across multiple zones, and timezone difference tools. Adds date arithmetic, date differences, and business-day counting, plus cron parsing, validation, generation, and next-run calculation. Also converts between Unix timestamps and readable dates, and formats, parses, and counts down durations.
- When to use it
- Useful when an assistant needs reliable date and time arithmetic, timezone conversions, cron schedule explanations, or timestamp conversions instead of estimating them. Worth adding for scheduling, logging, or cross-timezone work where exact values matter.
- Requirements
- Runs locally as a Node.js process over stdio; the npm package @rog0x/mcp-time-tools must be installed and built, and the server is started with node pointing at its built entry file. No accounts, API keys, or network access are declared.
Installation
In SourceWeft
- Open Time in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
README
mcp-time-tools
Date, time, and timezone tools for AI agents via the Model Context Protocol (MCP).
Built entirely with native JavaScript Date and Intl APIs -- no external date libraries required.
Tools
Timezone Converter
- convert_timezone -- Convert a date/time from one timezone to another
- list_timezones -- List common timezones with current UTC offsets
- current_time_multi -- Show current time in multiple timezones at once
- time_difference -- Calculate the time difference between two timezones
Date Calculator
- date_add_subtract -- Add or subtract days, weeks, months, or years from a date
- date_difference -- Calculate the difference between two dates in various units
- business_days -- Count business days between dates or add business days to a date
Cron Parser
- parse_cron -- Parse a cron expression into a human-readable description
- cron_next_runs -- Calculate the next N execution times for a cron expression
- validate_cron -- Validate a cron expression and explain any errors
- generate_cron -- Generate a cron expression from a human-readable description
Timestamp Converter
- timestamp_to_date -- Convert Unix timestamp (seconds or milliseconds) to readable formats
- date_to_timestamp -- Convert a date/time string to Unix timestamps
- current_timestamp -- Get the current Unix timestamp and formatted date/time
Duration Formatter
- format_duration -- Convert seconds to human-readable duration (e.g. 2h 30m 15s)
- parse_duration -- Parse a human-readable duration string to seconds
- time_ago -- Calculate relative time description (e.g. "5 minutes ago")
- countdown -- Calculate time remaining until a target date/time
