Okay, I have some more information on this.
The error only occurs for some very particular outputs of timeofday().
Namely, Saturdays.
No I'm not kidding.
When I tried to diagnose the problem today (Sun Aug 07), everything worked fine.
I was able to replicate the error, however, by deliberately specifying
yesterday's timeofday() string:
=> select timeofday()::timestamp;
timeofday

From the last few examples, you can see that the conversion succeeds
when "Sat" is present at the start, or when the timezone is present at
the end, but not when both are present, as in the timeofday() output.
Perhaps the parser is treating the string "Sat" as a timezone token?
