This package provides GPS time conversion utilities, including a gpstime subclass of the built-in datetime class with the addition of GPS time parsing and conversion methods.
Leap second data, necessary for GPS time conversion, is expected to be provided by the core libc Time Zone Database tzdata (on linux). If for some reason the tzdata leapsecond file is not available, a local cache of the IERS leap second record will be maintained:

The package can be executed as a command-line GPS conversion utility. In this manor it is a rough work-alike to the LIGO "tconvert" utility.
