Subject: [PATCH] tests/test_util: Fix wrong argument in `delta`

This spewed errors because the `math` invocation got no second
operand:

    Testing file checks/sigint.fish ... math: Error: Too few arguments
    '1571487730 -'

but only if the `date` didn't do milliseconds, which is the case on
FreeBSD and NetBSD.

(also force the variable to be global - we don't want to have a
universal causing trouble here)
