Time question

[pancake101]

Hi

I had a notice saying that the water was going to be interrupted and to prepare for it. The notice said .........................

it will be necessary to interrupt your water supply between the following dates and times:

Tuesday 26th June 2018
Mid-night to 04.00 hours.

Ok - so which evening should I have got a bucket or water ready and filled the kettle before going to bed. It appears that myself and a neighbour were ready on different nights. Either way the water cut did not affect either of us!

Thanks Pancake

I would say Monday night, Tuesday morning.

Midnight is 00:00, not 24:00. So both those times are on Tuesday morning.

Although the BBC would apparently disagree because their Tuesday weather forecast runs 0600 to 0600

Thanks Gryffron - I was doubting my ability to understand English.

They must be BBC watchers!

There is a worse confusion: whether noon is 12.00 a.m. or 12.p.m
In principle it is neither because the sun is theoretically overhead at 12.00 - on the meridian - and thus not ante- or post- meridiem.
Thank goodness for the 24-hour clock.

It would have been less confusing if someone at the water company had been educated to know that 00.01 is when the day begins and 24.00 is when it ends, so there is no 00.00.

I think you mean that the day begins and ends at 24:00, so there is no 00.00, otherwise I am terribly confused.

Though this page seems to disagree:

Some of us, who have got some service in, will know instinctively that midnight is 23:59. If you returned to camp after that time you were AWOL. Hence midnight is the end of the day, not its beginning.

ISO8601 refers.
Midnight is a special case and may be referred to as either "00:00" or "24:00". The notation "00:00" is used at the beginning of a calendar day and is the more frequently used. At the end of a day use "24:00". "2007-04-05T24:00" is the same instant as "2007-04-06T00:00

In the case of Tuesday 26 June, the start of the day is 20180625 0000 (which is also 20180624 2400)

Purely logically, I would say that the opposite is the case and that 24:00 is no more correct than 23:60. It is merely convention that legitimises it.

Also, from a practical standpoint, a digital clock normally changes on the minute or on the second. For example, a clock may change from 23:59 to 00:00 at midnight and stay that way for a whole minute. If it says 00:00, it is within the first minute of the day, not at the end.

If you ignore the ambiguous 0:00 part, they have said the work is on Tuesday and most of it will occur between 00:01 and 04:00 so I think it's most likely to be on Tuesday AM and not Wednesday AM.

This is of course the same argument as was waged at the beginning of the new millennium. Look up the arguments at that time. For the OP's query, I think it is fairly obvious that they intended to convey the info that the water supply would be interrupted on Tuesday, early morning. Not that it would affect many of us anyway I suppose.

It’s actually not the same argument at all. The issue with the millenium was that two thousand years earlier there was no zeroth year at all — only a 1BC followed immmediately by 1AD. There is always a zeroth minute of the day. The argument is only about what to call it.

There were two discussions at the time. One about the year and the other about the time. Dod was clearly talking about the time the new Millennium should have been ushered in.

I think.

Ah, I missed that one at the time. Must have been too busy celebrating...

GS

[Dod101]

Precisely so. There was certainly an argument about which year should have ushered in the new millennium and the other about the day, but essentially I see it as the same argument. What time or when does a particular period start. Of course if you are into the latest Carlo Rovelli book, The Order of Time, you will know that it is irrelevant anyway, because he reckons that it does not really exist (although someone will no doubt correct my understanding) Sorry mod, this is getting away from Dak?

It is. I think the OP's query has been well discussed and answered. Chris
