Carbon converts 12:00 to wrong time












0














It seems Carbon converts 12:00 (24:00) vice versa when the format is "H a":



$time = Carbon::createFromFormat("H a", "12 AM")->toTimeString(); // "00:00:00"

$time = Carbon::createFromFormat("H a", "12 PM")->toTimeString(); // "12:00:00"


Why it does that and is there any way to avoid this or maybe I'm doing something wrong?

    Wrong? According to which convention? If you want to be unambiguous, just avoid am/pm formats.

  • Try it with 11:59 instead. 12 is not a good number to test using am/pm times

  • @Amadan Oh, all the time I thought that 12 AM = 12:00, 12 PM = 00:00, so it's actually working right. Thanks, my life will never be the same ))

  • It is, in Japan. In USA, it doesn't make sense (12PM is noon, continuing numbering from the morning, and taking PM from afternoon) but it is what it is. 24-hour clocks ftw.

Monofisismo

Image
Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

Olmecas

Image
Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
