libtai supports two time scales: (1) TAI64, covering a few hundred
|
||
|
|
billion years with 1-second precision; (2) TAI64NA, covering the
|
||
|
|
same period with 1-attosecond precision. Both scales are defined
|
||
|
|
in terms of TAI, the current international real time standard.
|
||
|
|
|
||
|
|
libtai provides an internal format for TAI64, struct tai, designed
|
||
|
|
for fast time manipulations. The tai_pack() and tai_unpack() routines
|
||
|
|
convert between struct tai and a portable 8-byte TAI64 storage
|
||
|
|
format. libtai provides similar internal and external formats for
|
||
|
|
TAI64NA.
|
||
|
|
|
||
|
|
This version of libtai requires a UNIX system with gettimeofday().
|
||
|
|
It will be easy to port to other operating systems with compilers
|
||
|
|
supporting 64-bit arithmetic.
