From 71d6a02ca19857a06bc789f09c885e5cd77f7212 Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Fri, 18 Feb 2022 12:49:59 +0300 Subject: refactor(journaldriver): Use time crate directly instead of chrono With this change, we still depend on chrono (through medallion), but but I'm going to try and fix that upstream as well.
