6.10.2.2 Time Functions

All time reporting functions report the absolute time value (as if time would be positively defined). Time orientation (or sign, or signedness) may be obtained via `t_sign'.

• void `t_copy'(time t, time s);

  sets t to s

• mode `t_d_hour'(time t);

  is the t hour of the day (0 .. 23)

• mode `t_day'(time t);

  is the t day

• void `t_ddiff'(time t, date d, date e);

  sets t to the d e difference (the sign of the difference is preserved)

• void `t_fix'(time t, mode second, mode microsecond);

  sets t to second seconds and microsecond seconds. The absolute value of microsecond is not restricted to the 0 .. 999999 range. Both second and microsecond may be negatively defined.

• mode `t_h_minute'(time t);

  is the t minute of the hour (0 .. 59)

• mode `t_m_second'(time t);

  is the t second of the minute (0 .. 60)

• mode `t_microsecond'(time t);

  is the t microsecond

• mode `t_s_frame'(time t);

  is the t frame of the second (0 .. 59) (here frame is the sixtieth part of the second)

• mode `t_second'(time t);

  is the t second

• void `t_set'(time &t, time h);

  sets the t time object as a reference of the h time object

  The function is generated on request only.

  See Time Library Generation Flags.

• mode `t_sign'(time t);

  is -1 if t is negatively defined, 1 if t is (strictly) positively defined and zero if t is zero
