Problem Statement
Time unit conventions are inconsistent across PPL commands, causing confusion and making queries non-portable between commands.

Current State
Case sensitivity inconsistencies:

• bin command: M = minutes
• stats command: M = months

Command-specific time units:

• bin command supports: US (microseconds), CS (centiseconds), DS (deciseconds)
• stats command: does not support these subsecond units

Long-Term Goals

• Establish consistent time unit conventions across all PPL commands
• Enable portable queries that work consistently across different commands
• Provide comprehensive time unit support where appropriate
• Maintain backward compatibility while addressing inconsistencies

Proposal
Standardize time unit support across PPL commands:

1. Consistent case sensitivity:

   • m = minute
   • M = month

2. Unified time unit support:

   • Add missing subsecond units (us, cs, ds) to commands where appropriate
   • Ensure consistent abbreviations and full names across commands
