Why can a hockey log show a goal or penalty a second earlier than the displayed clock?
The NHL glossary says a goal or penalty in the last minute is rounded to the previous second. That convention can explain a one-second difference when a source shows tenths and a listing shows whole seconds, but the glossary alone does not identify the display method used by a particular game or provider.

The page describes a whole-second convention
The NHL glossary’s “Tenths of a Second” entry says that a goal or penalty occurring in the last minute is rounded to the previous second. Its example shows why a whole-second event listing can appear one second earlier than a clock that preserves tenths.
This is a statement on the NHL glossary page, not proof that every live clock, game log, league, or data provider applies the same display. The page shows no publication date or version, so keep the explanation tied to its wording.
Compare the time precision before calling it a conflict
A clock showing tenths and a record showing whole seconds do not present identical precision. Before treating a one-second difference as a contradiction, check whether the event occurred in the last minute, whether the displayed number is elapsed or remaining time, and whether the source uses a whole-second convention.
The glossary’s note does not explain review corrections, synchronization between devices, or a provider’s event-time pipeline. It is one documented explanation to check, not a diagnosis of a particular record.
Make the period and clock assumptions explicit
If you illustrate the convention, state the assumed period length, the event’s remaining time, and whether the calculated timestamp is elapsed time. Those inputs prevent the example from being mistaken for a real event or a universal timing rule.
No current BSD event feed or metric availability is asserted here. The guide is limited to the NHL glossary’s displayed timing note and a transparent arithmetic example.
A hypothetical whole-second listing
With an assumed 20:00 period, a fictional penalty with 12.4 seconds remaining corresponds to 19:47.6 elapsed. If the whole-second display follows the NHL glossary’s previous-second convention, it shows 19:47 rather than 19:48. This hypothetical arithmetic illustrates the glossary wording only; it is not a real event or a claim about a particular broadcast, league feed, or provider.
Related questions
Does the NHL glossary say every event time is rounded this way?
No. The displayed entry names goals and penalties in the last minute. It does not establish a universal rule for every timestamp, provider, broadcast clock, or other league.
Does a one-second difference prove that a game record is wrong?
No. The glossary documents one possible display convention, but it does not identify how a particular source generated its time. Check the source, precision, and applicable event records before drawing a conclusion.
