Detailed Description

Fundamental type definitions for time-related data.

This group defines the core time representations used throughout the library, including timestamps, fractional time units, Julian dates, and time zone offsets.

Type Categories

Unix-based timestamps: ts_t, ts_ms_t, ts_us_t
Fractional and floating-point time: fts_t, oadate_t, jd_t
Julian date types: jd_t, mjd_t, jdn_t
Utility units: year_t, dse_t, tz_t

Example Usage

time_shield::ts_t now = 1700000000;      // Unix timestamp in seconds
time_shield::fts_t precise = 1700000000.123; // Time with fractional seconds
time_shield::jd_t julian = 2459580.5;     // Julian Date
time_shield::tz_t offset = 180;           // UTC+3 in minutes
