Time Calculations

1. Overview

Mac-Auth relies on strict UNIX epoch timestamps to control interval flow and time-based calculations.

2. Core Mathematical Conversions

Epoch Parsing

  • Extracts time in seconds using epoch format

    unix_timestamp(now()) - unix_timestamp(LASTRSTTIME)

  • Produces elapsed time in seconds

Interval Tracking (RstInterval)

  • Tracks interval values uniformly in seconds

  • Maintains consistent time boundaries

  • Ensures accurate interval mapping

End of Interval Caps

  • Calculates remaining interval time

    RstInterval - ElapsedTime

  • Prevents overflow beyond defined limits

Session Boundary Caps

  • Applies final constraints using Timespan

  • Ensures session limits are not exceeded

  • Wraps calculations within defined boundaries
