将日期舍入到最接近的 5 分钟时刻作为数组

Question

我需要使用 Date() utc 将时间四舍五入到最接近的五分钟，然后将其作为数组推送

示例：

[
  "2019_10_9_00_05",
  "2019_10_9_00_10",
  "2019_10_9_00_15",
  "2019_10_9_00_20",
]

代码

const now = moment();

const time= [];

for (let i = 0; i < 4; i++) {
  now.add(5, 'minutes');
  time.push(now.utcOffset(-1).format('YYYY_M_DD_HH_mm'));
}

console.log(time);

输出

[
  "2019_10_9_00_03",
  "2019_10_9_00_7",
  "2019_10_9_00_11",
  "2019_10_9_00_16",
]

请有任何解决方案

Answer 1

您需要先检查分钟值是否是 5 的倍数。

    const now = moment();
    const factor = 5;
    const time = [];

    const minutes = now.minutes();    
    if (minutes !== 0 && minutes % factor) {  // Check if there is a remainder
      const remainder = minutes % factor;     // Get remainder

      now.add(factor - remainder, 'minutes'); // Update minutes value to nearest 5
    }

    for (let i = 0; i < 4; i++) {
      time.push(now.utcOffset(-1).format('YYYY_M_DD_HH_mm'));
      now.add(5, 'minutes');
    }

    console.log(time);

结果：

now: 2019_10_11_09_19
["2019_10_10_21_20", "2019_10_10_21_25", "2019_10_10_21_30", "2019_10_10_21_35"]
