[ZLLentz]

Expected Behavior

Tests should always pass!

Current Behavior

See pcdshub/pcds-envs#253

tests/test_daq.py:330: AssertionError

Possible Solution

• Extend the range of acceptable timings
• Make our timing check more accurate
• Rework the test
• Remove the test

Steps to Reproduce (for bugs)

1. Run the test suite on a slow server

Context

Probably low priority. This adds some noise to the pcds-envs unit testing suite.

Your Environment

pcds-5.5.0
