We propose a dynamic verification framework for protocols in real-time distributed systems. The frame-
work is based on Scribble, a tool-chain for design and verification of choreographies based on multiparty session
types, which we have developed with our industrial partners. Drawing from recent work on multiparty session types
for real-time interactions, we extend Scribble with clocks, resets, and clock predicates in order to constrain the times
in which interactions occur. We present a timed API for Python to program distributed implementations of Scribble
specifications. A dynamic verification framework ensures the safe execution of applications written with our timed
API: we have implemented dedicated runtime monitors that check that each interaction occurs at a correct timing
with respect to the corresponding Scribble specification. To demonstrate the practicality of the proposed framework,
we express and verify four categories of widely used temporal patterns from use cases in literature. We analyse the
performance of our implementation via benchmarking and show negligible overhead.
