如何检查期间中日期的出现

In my Go application, I am trying to check the occurrence of a date in a period.

if survey.StartPeriod.Before(time.Now()) && survey.EndPeriod.After(time.Now()) {
    fmt.Println("1 BLOCK")
}
else if survey.EndPeriod.Before(time.Now()) {
    fmt.Println("2 BLOCK")
}

If I have such incoming data (current time inside period):

Current TIME | 2019-03-28 21:02:47.0377305 +0600 +06 m=+60.748044601
START_PERIOD | 2019-03-28 21:00:00 +0000 +0000
END_PERIOD   | 2019-03-28 21:05:00 +0000 +0000

I want to run code inside 1 block. My current code run that block only if I use Before function to both periods. I am not sure that it's correct.

If I have such incoming data (current time outside the end_period):

Current TIME | 2019-03-28 21:10:47.0377305 +0600 +06 m=+60.748044601
START_PERIOD | 2019-03-28 21:00:00 +0000 +0000
END_PERIOD   | 2019-03-28 21:05:00 +0000 +0000

I want to run code inside 2 block. Right know it works incorrect. How to correctly make this program logic?

EDIT:

As you can see CURRENT_TIME inside range.

CURRENT_TIME | 2019-03-29 08:32:06.1375323 +0600 +06 m=+60.318452301
START_PERIOD | 2019-03-29 08:30:00 +0000 +0000
END_PERIOD   | 2019-03-29 08:31:00 +0000 +0000

When I try to test function InTimeSpan it return false value which is not correct. I am really confused. Why it happens?!

log.Println(InTimeSpan(survey.StartPeriod, survey.EndPeriod, time.Now()))
// return false

What you are currently checking is if your current time is in the given range. You might want to swap time.Now with another time to check the occurrence of the date.

However a couple things to consider:

• make this logic to an outside function, as it needs to respond with true or false only, something like this it is as easy as:

func InTimeSpan(start, finish time.Time, timeToCheck time.Time) bool {
    return start.Before(timeToCheck) && finish.After(timeToCheck)
} 

• make all times to the same timezone. Might be helpful if the timezone of the time you are checking is different, and this avoids some of the edge cases, something like this:

func InTimeSpan(start, finish time.Time, timeToCheck time.Time) bool {
    return start.UTC().Before(timeToCheck) && finish.UTC().After(timeToCheck)
}
