With some late/extreme stages of ADHD you basically need to drink coffee to go to sleep and consume sleeping pills to not to.

[–] aeronmelon@lemmy.world 78 points 1 day ago (2 children)

Don’t ever say “16 o’clock” ever again.

[–] CyberEgg@discuss.tchncs.de 73 points 1 day ago (1 children)

Okay, it's gonna be 17 o'clock next time then.

Missed opportunity for 00:30 O'Clock

24:00 o'clock, just to anger everyone

[–] halfdane@piefed.social 13 points 1 day ago (1 children)

Okay 🤷

But what about 20 o'clock?

Most european o'clock 😂

[–] ImWaitingForRetcons@lemmy.world 46 points 1 day ago (2 children)

Even for people who can sleep after drinking a ton of caffeine, it so negatively impacts your sleep quality, so you should still avoid it if possible.

[–] Zorsith@lemmy.blahaj.zone 11 points 1 day ago

aww, but i like power napping

[–] chocrates@piefed.world 6 points 1 day ago

I sometimes have to mortgage my future (sleep) so I can sell my body to th capitalists tho.

[–] s@piefed.world 17 points 1 day ago (2 children)

Where in the world is it standardized to write times like that?

[–] Zwiebel@feddit.org 24 points 1 day ago* (last edited 1 day ago) (4 children)

Europe I guess? We like 24h time

[–] olenkoVD@lemmy.dbzer0.com 2 points 16 hours ago

This is not true for all of Europe however!

[–] k0e3@lemmy.ca 12 points 1 day ago (9 children)

Do you guys say "16 o'clock?" I'm used to the 24h tube since I live in Japan, but I find myself always going back to 12h like I did in Canada where I grew up. So saying 16 o'clock in English sounds a bit unnatural for me. But I also have no problem saying 16 heure in French. Old habits die hard I guess.

[–] CyberEgg@discuss.tchncs.de 14 points 1 day ago* (last edited 1 day ago)

I say "sechzehn Uhr" but drop the "Uhr" when adding Minutes ("sechzehn dreißig" for 16:30), except before 13:00 ("neun Uhr" for 09:00 and "neun Uhr dreißig" for 09:30) because it flows more easily. But some people keep the "Uhr" even after 13:00 (it's the official way).
Written standard though is to put "Uhr" behind all the numbers ("neun Uhr dreißig" is written as "09:30 Uhr").

[–] moopet@sh.itjust.works 7 points 1 day ago (1 children)

Where I am I'll write 16:00 and read it aloud as "4 o'clock"

[–] tigeruppercut@lemmy.zip 2 points 1 day ago

That's my preferred method as well. I like 24 hr time for writing but I'd never say it out loud, May e bc I didn't grow up saying it.

[–] observantTrapezium@lemmy.ca 7 points 1 day ago

I'm from English speaking Canada and I'm doubling down on 24h and metric.

16'o'clock is still weird AF.

[–] AbsolutelyNotAVelociraptor@sh.itjust.works 5 points 1 day ago (1 children)

Look at them europeans bragging about their ability to count beyond 12 hours!

/s (I'm european too, I find it funny that people get confused with 24h time format)

[–] Onomatopoeia@lemmy.cafe 7 points 1 day ago (1 children)

Its not the 24 hr time, its saying it with "o clock" that's weird

O'clock is pretty british. HH:MM is normal in the more civilised areas of Europe (aka the rest of Europe).

[–] MalReynolds@slrpnk.net 13 points 1 day ago* (last edited 1 day ago) (3 children)

Generally O'Clock is used with a 12 hour clock and AM/PM is implied by context, if you need specificity use millitary time (i.e 24 hr clock - 1600). As an Australian I find 16 O'Clock a bit jarring.

[–] CyberEgg@discuss.tchncs.de 12 points 1 day ago* (last edited 1 day ago) (1 children)

I'm from Europe. I use a 24h-clock but not military time. Military time is an anglophone thing I don't care about since I'm not in the military. And frankly, I don't care much about how Australians or US-Americans or English people find my time and date formats or any other unit or measurement jarring, because you guys rarely agree on any kind of measurements, so I use metrics, a 24h-clock (maybe add an "o'clock" because it reads nicer to me) and dd.mm.yy(yy) instead of stones, pounds, feet or freedoms per square ketchup ¯\_(ツ)_/¯

[–] MalReynolds@slrpnk.net 3 points 1 day ago (1 children)

Whatever, you do you. We're 100% metric btw.

[–] CyberEgg@discuss.tchncs.de 11 points 1 day ago (1 children)

We're 100% metric btw.

Canada, UK and USA aren't, at least not in colloquial language. That's what I mean. You post something in english and always meet someone from some anglophone country doing it differently. So I stopped caring.

[–] waz@feddit.uk 3 points 1 day ago* (last edited 1 day ago) (1 children)

So what’s wrong with kg for weighing things, st & lb for people, miles for driving distance, metres for building things, C for temperature and feet for ascent of hills and stuff? That’s what a 70’s born UK kid thinks like. So 16:15 is said out loud, quarter past four, maybe rarely 1615, but never 16 o’clock and? No. O’clock is only on the hour. If it’s got bits on the end you say everything except the ‘o’clock’ But I love what you’ve done with ‘half-four’ to mean 3.30. I really enjoy doing that with my German colleagues.

What's right about it?

But I love what you’ve done with ‘half-four’ to mean 3.30. I really enjoy doing that with my German colleagues.

That's not exclusively german though as germanic languages in general and some slavic languages use this format.

[–] ekky@sopuli.xyz 12 points 1 day ago (1 children)

First of, in Europe we use ISO 8601, which is quite different from the military time which the USA uses.

Second, in my home country we still say "16 on the clock" or "15:45 on the clock" (just translated to the native language, eg. "Klokken 16") to signify we're talking time and not weight or distance.

[–] MalReynolds@slrpnk.net 3 points 1 day ago

You said

O’clock is pretty british

I was speaking to that (Australia is very similar).

[–] fonix232@fedia.io 9 points 1 day ago (3 children)

military time is NOT 24 hour time! Stop mixing the two.

military time doesn't use minutes and hours but rather merges the two - 16:45 becomes 1645, and so on.

24 hour time still distincts minutes and hours.

[–] folekaule@lemmy.world 5 points 1 day ago

100% this. I was going to post what you said as well. But I will add that in the US, if you use 24 hour time, most people just refer to it as military time. If you tell them the difference they don't really care.

In the US 24h is virtually never used in a civil context, but in scientific, engineering, and medical contexts it is ubiquitous.

[–] MalReynolds@slrpnk.net 5 points 1 day ago

Valid, but hardly deserving of significant argument. Actually considered that in my original post but decided that it gets the point across. I now regret the whole thing, ppl take it way too seriously.

Peace, out.

I have severe adult adhd and this has never been the case for me.

[–] moopet@sh.itjust.works 7 points 1 day ago (1 children)

Caffeine used to make me sleepy. I'd often have a cup straight before bed. As I get older it doesn't have such a noticable effect on my but even black sugarless coffee really makes low blood sugar issues worse. If I drink it first thing in the morning and eat anything sugarry I'll crash 20 minutes later.

I get a small rush for a few hours and then crash, usually helps me sleep better in the long run.

[–] Dagnet@lemmy.world 4 points 1 day ago (2 children)

I get nothing from it, still feel tired and sleepy. But it stops me from sleeping, it's the worst of both worlds

[–] richie_golds@lemmy.ca 2 points 14 hours ago (1 children)

I get that too. I can have an energy drink and a coffee in the morning and still feel the need to sleep, but if I do much as have a small cup of tea late at night I don’t sleep.

[–] Dagnet@lemmy.world 1 points 12 hours ago

Weirdly enough energy drinks work for me but I crash HARD when the effect wears off. I avoid them as much as possible

It's funny how much if a spectrum there is. My wife gets stuck awake if she has caffeine after 3pm, and I have fallen asleep on nodoze more than once.

[–] Ioughttamow@fedia.io 5 points 1 day ago

It was funny, at a work meeting a few months ago someone was having some coffee, and the director and a bunch of others chimed in that if they had coffee that late (11am) they wouldn’t be able to sleep later.

[–] em2@lemmy.ml 4 points 1 day ago

As if I could fall asleep that easy regardless of caffeine intake or not ;_;

[–] slazer2au@lemmy.world 3 points 1 day ago

Those lucid dreams I had after drinking a sugar free monster after dinner were something else.
