Discreetly tucked away in the corner of almost every stand in every primary GAA county ground in the country is a hooter system, complete with wiring, lying as obsolete as some of those electronic voting machines commissioned for election purposes in 2002.
Like the electronic voting machines, the hooter systems were never put into widespread use. Unlike the electronic voting machines, subsequently scrapped at a colossal financial loss to the State, the fate of the hooter systems is not so clear.
Twice in the last decade, GAA Congress approved their use on foot of motions from counties and the Football Review Committee and twice Central Council subsequently advised against it, once in 2010 on the basis of cost and then in 2014 when a number of concerns, trends and anomalies were identified after a series of road-tests in third-level competitions.
The GAA's Central Competition Controls Committee put together two reports at either end of 2014, one which identified the need to capture substitutions as part of the overall stoppage equation and the need to conclude a game when the ball had gone dead (over a sideline or end line) because of concerns over the establishing the genesis of a relevant score if a hooter was sounded on the 70-minute mark simultaneously.
Later that year more problems were highlighted by those who oversaw the trial, some considered potentially "reputational" to the games. Human error, systems failure, fouling down the clock, negative possession where teams ran down the clock as it neared the 70-minute mark, intense media scrutiny and the requirement to stop the clock for everything were seen as drawbacks to the overall plan.
By Congress 2015, the original successful motion had been rescinded and the stop clock/hooter was out of favour once more.
Every so often, though, its potential use surfaces. When Armagh visited MacHale Park in Castlebar for a qualifier game last summer there were clear discrepancies between the time allowed at the end of it and the time that actually should have been played.
Mayo won by a point, four minutes were scheduled to be added - it lasted five-and-a-half minutes but with the number of stoppages due to injury that could well have been eight.
Earlier this year the second half of the All-Ireland club final between Corofin and Kilcoo stretched to 11 minutes, while over the weekend there was a renewed focus on timekeeping with managers expressing frustration.
Monaghan manager Seamus McEnaney didn't bite on it too hard but the three extra minutes (and five seconds) that allowed Dublin to equalise were seen as generally contentious.
Drill down into it, however, and within that first extra six minutes called were two stoppages lasting 90 seconds each.
That's three minutes which, with the original six, equates to the nine which were played by referee Ciarán Branagan. Did anyone honestly expect him to blow exactly on nine minutes with Davy Byrne ready to pull the trigger?
In Letterkenny, despite being content with a win on the road against Donegal, Galway manager Pádraic Joyce was perplexed with the amount of time that Joe McQuillan allowed at the end of the second half.
Initially, five minutes were called but by the time Michael Murphy's free to equalise curled narrowly wide, 77 minutes and 25 seconds had elapsed.
McQuillan was perfectly entitled to add on that extra time because of the delay caused by Michael Boyle's collision with Eoghan Bán Gallagher that took two minutes before Ciarán Thompon's free went wide. The foul on Ryan McHugh for the Murphy free happened within those seven minutes.
Any query over the initial five minutes is easily accounted for: 1.20 for deliberation over a disallowed Murphy point, 35 seconds to red card Galway's Michael Daly after his second yellow foul on Caolan Ward, 45 seconds to yellow-card Galway's Michael Boyle, one minute for Shane Walsh to convert a free after Donegal's Paul Brennan hacked down Damien Comer, for which he was black-carded, 1.10 to deal with Galway's Ronan Ó Beoláin's sliding tackle on Dara Ó Baoill.
Meath's Andy McEntee also raised concerns with referee Sean Hurson's timekeeping in Navan and he had perhaps the most legitimate issue, given that only 10 seconds were played beyond the four minutes signalled when those four minutes includes a break in play for an injury to Mayo's Bryan Walsh which took him 30 seconds to gather himself together before the free was taken 15 seconds later, 45 seconds in all. At the very least, another 20 seconds was due, small but potentially consequential nonetheless.
There isn't a major timekeeping issue in the GAA as some suggest and, generally, most referees are getting it right.
But the problems identified in both reports should not be insurmountable. Teams run down the clock and foul it down anyway, irrespective as to whether a clock is counting down in front of them. The suggestion that every break in play should see the clock stop isn't required. With substitutions, those stoppages are already written in, 20 seconds each.
What reviving the stop clock and hooter would do is bring clarity to this area in the same way that Hawk-Eye has successfully done with the legitimacy of points at two venues.
It would require extra personnel with a fifth official, a communications systems to link the referee and the fifth official and the unpalatable sight of a team kicking a ball out over a sideline to conclude a game.
Ultimately, referees are the biggest stakeholders. They have a lot on their plate, this might be an aid they could fall back on but there are bigger issues that the men in black have to deal with than time.
