majiayu000 Current Date
Get the current UTC date and time to ensure correct temporal context for all operations.
CRITICAL EXECUTION REQUIREMENT
This skill requires COMMAND EXECUTION, not assumption-based answers.
When this skill loads, you MUST:
- EXECUTE the bash command shown in Quick Start section below
- REPORT the actual command output (not an assumed date)
- NEVER state a date from memory or assumptions
- NEVER skip execution thinking "I know the date"
Why this matters: This skill exists precisely because date assumptions are unreliable. Model training cutoffs, context issues, and stale information mean assumptions about "today" are frequently wrong. The ONLY reliable source is executing the date command and reporting actual output.
Overview
This skill provides a simple, reliable way to verify the current date and time. It addresses situations where Claude Code or subagents may have incorrect assumptions about the current date due to model training cutoffs.
Why a dedicated skill?
- Date/time assumptions are unreliable due to model training cutoffs
- This skill enforces execution-based verification instead of guessing
- Essential for time-sensitive operations (deadlines, versioning, temporal ordering)
What this skill does NOT do:
- Time zone conversions
- Time arithmetic or duration calculations
- Date parsing or validation
When to Use This Skill
IMPORTANT: This is an execution-only skill. Always run the command; never state dates from memory.
Use this skill when:
- Starting a new task or conversation
- Working on time-sensitive operations (deadlines, schedules, versioning)
- Verifying temporal context before making date-based decisions
- Correcting date misunderstandings during a conversation
- Needed by subagents to establish correct date context
- Creating timestamps or version numbers
- Writing documentation with "Last Verified" dates
Quick Start
Get current UTC date and time:
date -u +"%Y-%m-%d %H:%M:%S UTC (%A)"
Expected output:
2025-11-09 18:31:10 UTC (Sunday)
Format explanation:
2025-11-09- ISO 8601 date format (YYYY-MM-DD)18:31:10- 24-hour time with seconds (UTC)UTC- Coordinated Universal Time(Sunday)- Day of week
Execution Checklist:
- Execute the command (don't assume the date)
- Verify output includes UTC timezone
- Report actual output (not paraphrased)
Usage Patterns
At Task Start
date -u +"%Y-%m-%d %H:%M:%S UTC (%A)"
# Then proceed with task...
For Documentation
date -u +"%Y-%m-%d"
# Use for "Last Verified" dates
For Timestamps
date -u +"%Y%m%d-%H%M%S"
# Use in filenames
Best Practices
- Always use UTC: Avoid timezone confusion
- Run at task start: Verify date when beginning time-sensitive work
- Share with subagents: Include current UTC date in Task agent prompts
- Use ISO 8601 format: Unambiguous, internationally recognized
