Re: Postgres storing time in strange manner

I said:

BTW, some digging in the assembly code shows that the actual problem is
this: instead of emitting "x / 3600.0", with -ffast-math the compiler
emits the equivalent of "x * (double) (1.0 / 3600.0)".  It's the
last-bit inaccuracy of the latter constant that's killing us.
