Time

Time and timezone conversion utilities. Standalone CLI only (no MCP dependency).

Execution Methods

Run scripts/time_cli.py via Bash:

# Prerequisites: pip install pytz (or use Python 3.9+ with zoneinfo)

# Get current time in a timezone
python scripts/time_cli.py get --timezone "Asia/Shanghai"
python scripts/time_cli.py get --timezone "America/New_York"
python scripts/time_cli.py get  # Uses system timezone

# Convert time between timezones
python scripts/time_cli.py convert \
  --time "16:30" \
  --from "America/New_York" \
  --to "Asia/Tokyo"

# List available timezones
python scripts/time_cli.py list [--filter "Asia"]

Tool Capability Matrix

| Tool | Parameters | Output | |------|------------|--------| | get_current_time | timezone (required, IANA name) | {timezone, datetime, is_dst} | | convert_time | source_timezone, time (HH:MM), target_timezone | {source, target, time_difference} |

Common IANA Timezone Names

| Region | Timezone | |--------|----------| | China | Asia/Shanghai | | Japan | Asia/Tokyo | | Korea | Asia/Seoul | | US East | America/New_York | | US West | America/Los_Angeles | | UK | Europe/London | | Germany | Europe/Berlin | | France | Europe/Paris | | Australia | Australia/Sydney | | UTC | UTC |

Workflow

Getting Current Time

Identify target timezone (use IANA name)
Call get_current_time with timezone parameter
Response includes ISO 8601 datetime and DST status

Converting Time

Identify source timezone and time (24-hour format HH:MM)
Identify target timezone
Call convert_time with all parameters
Response includes both times and time difference

Output Format

get_current_time Response

{
  "timezone": "Asia/Shanghai",
  "datetime": "2024-01-01T21:00:00+08:00",
  "is_dst": false
}

convert_time Response

{
  "source": {
    "timezone": "America/New_York",
    "datetime": "2024-01-01T16:30:00-05:00",
    "is_dst": false
  },
  "target": {
    "timezone": "Asia/Tokyo",
    "datetime": "2024-01-02T06:30:00+09:00",
    "is_dst": false
  },
  "time_difference": "+14.0h"
}

Error Handling

| Error | Recovery | |-------|----------| | Invalid timezone | Check IANA timezone name spelling | | Invalid time format | Use 24-hour format HH:MM | | MCP unavailable | Fall back to CLI script |

Anti-Patterns

| Prohibited | Correct | |------------|---------| | Use city names directly | Use IANA timezone names (e.g., Asia/Tokyo not Tokyo) | | Use 12-hour format | Use 24-hour format (e.g., 16:30 not 4:30 PM) | | Assume timezone | Always specify timezone explicitly |
