The time in Eorzea is ….
The weather in Eorzea can be predicted. First, the number of Eorzean hours and days since the Unix epoch is calculated.
// Get seconds since Jan 1st 1970 const unixSeconds = Date.now() / 1000 // Get Eorzean hours/days since (1 Eorzean hour = 175 seconds) const eorzeanHours = Math.floor(unixSeconds / 175) const eorzeanDays = Math.floor(eorzeanHours / 24)
Next, compute which of the 3 time chunks the hour falls in.
let timeChunk = (eorzeanHours % 24) - (eorzeanHours % 8) // Adjust time chunk so that // 16:00 is 00, // 00:00 is 08, // 08:00 is 16 timeChunk = (timeChunk + 8) % 24
The number of Eorzean days and the time chunk form the seed that is hashed.
const seed = eorzeanDays * 100 + timeChunk // Do a little hashing const step1 = (seed << 11) ^ seed const step2 = (step1 >>> 8) ^ step1 // Return a number between 0-99 inclusive const weatherChance = step2 % 100
weatherChance computed as a number from 0 to 99, each zone can determine its weather. For example, the weather in Eureka Anemos is Gales if
weatherChance is between 30 and 59. Its full table of weathers is
