Currently, logs written by NCCL don't contain timestamp. We can elaborate on requesting them explicitly with: - [NCCL_DEBUG_TIMESTAMP_LEVELS](https://docs.nvidia.com/deeplearning/nccl/user-guide/docs/env.html#nccl-debug-timestamp-levels) - [NCCL_DEBUG_TIMESTAMP_FORMAT](https://docs.nvidia.com/deeplearning/nccl/user-guide/docs/env.html#nccl-debug-timestamp-format)
