Expected Output

works

Additional Information

• fails in 1.5.1 devel edce589
• works in 0.18.0

found this while debugging HCR issues, which uses low(Time) as initial value

EDIT: I found this code in nimhcr:

  proc sanitize(arg: Time): string =
    when defined(testNimHcr): return "<time>"
    else: return $arg

that may be related, in which case it should probably be fixed in PR that fixes this
