CL_dat_tai2utc

Description

• Converts the time (from 1950.0) of an event given in the TAI time scale (cjd_tai) into the time (from 1950.0) of the same event in the UTC time scale (cjd_utc).

• Notes:

  - The conversion from TAI to UTC uses internal predefined data that define the leap seconds.

  - If a leap second is added (normally the case), the UTC time between 23h59mn59.999... UTC (included) and 0h0mn0 UTC (excluded) cannot be represented; it is then %nan.

• See Dates and time scales for more details.

Parameters

cjd_tai:

Modified (1950.0) julian day in TAI time scale (1xN)

cjd_utc:

Modified (1950.0) julian day in UTC time scale (1xN)

Examples

cjd0 = CL_dat_utc2tai(21550); // ref time in TAI cjd_tai = cjd0 + (-15 : 15) / 864000; cjd_utc = CL_dat_tai2utc(cjd_tai); [(cjd_tai-cjd0)*86400; (cjd_utc-cjd0)*86400]'
