使用Go计算最接近的时间差，格式为HH:MM(am/pm)

package main

import (
    "fmt"
    "time"
)

func main() {
    targetTimeStr := "09:30am"
    targetTime, _ := time.Parse("03:04pm", targetTimeStr)
    currentTime := time.Now()

    timeDiff := currentTime.Sub(targetTime).Round(time.Minute)
    if timeDiff < 0 {
        timeDiff = -timeDiff
    }

    hours := int(timeDiff.Hours())
    minutes := int(timeDiff.Minutes()) % 60

    formattedTimeDiff := fmt.Sprintf("%02d:%02d%s", hours, minutes, getAMPM(currentTime))

    fmt.Println("最接近的时间差为:", formattedTimeDiff)
}

func getAMPM(t time.Time) string {
    if t.Hour() < 12 {
        return "am"
    }
    return "pm"
}
