[LEAPSECS] php breaks if UTC has no leap seconds?

The powers that be have awarded telescope time in a novel fashion,
so I'm plowing through the php code that publishes the schedules.
To my surprise I find that php has a method which thinks it knows
where the sun is
As near as I can tell, this method gives the UT of the various
daily events for a given location on earth.
Related to that is another method which thinks it knows the
local civil time of sunrise
Again, this appears likely to presume that the POSIX time_t
provides a useable value for UT.
This is the first example I've come across where a widely used
API will break if UTC does not continue to have leap seconds.
