If the astronomical term is what you want, then maybe you really do have a format that cannot be expressed in any existing notation, and maybe it really is worth burning a % notation. But how common is the Astronomical Julian Date in shell programming?I instinctively turned to 'date' for the full Julian date for astronomical purposes, but I concede that this is not an incredibly common use case.
I'd say that 'date' is the natural program to try for date manipulations. ;-)
GNU systems are very useful in scientific settings, IMHO adding full Julian date in the astronomical sense to 'date' further enhances this.
Thanks, Erik
