This software provides a reliable and cost-free solution for storing and managing time and date information. It simplifies the process of working with dates and times for various applications.
If you're looking for a library that supports incredibly precise time scales, libtai might just be what you need. It offers two scales - TAI64 and TAI64NA - both defined in terms of TAI, the international real time standard. TAI64 provides precision up to one second for a few hundred billion years, while TAI64NA covers the same period, but with 1-attosecond precision.
The library also provides an internal format for TAI64 - called struct tai - that is designed for fast time manipulations. If you need to convert between struct tai and a portable 8-byte TAI64 storage format, the library includes tai_unpack() and tai_pack() routines to make it easy.
For TAI64NA, libtai provides similar external and internal formats as well. Moving on, the library also includes struct caldate to make storing dates in year-month-day form easier. Struct caldate can be easily converted, under the Gregorian calendar, to a modified Julian day number for date arithmetic.
Struct caltime is another tool libtai has to offer. It stores calendar dates, times, and UTC offsets. If you need to convert from struct tai to struct caltime in UTC, accounting for leap seconds for accurate display, libtai has you covered. Interestingly, the library can also convert back from struct caltime to struct tai, making it a versatile tool for user input.
On top of all this, libtai speedily converts overall UTC-to-TAI, with a conversion speed that's 100x better than the usual UNIX mktime() implementation. All in all, this library seems like a fantastic choice if you need to handle precise time conversions and store dates in a reliable format.
