On: datetime.utcnow() is now deprecated

[38]

Go seems to work as expected here:

    package main
    
    import (
       "fmt"
       "time"
    )
    
    func main() {
       dt := time.Unix(0, 0).UTC()
       fmt.Println(dt) // 1970-01-01 00:00:00 +0000 UTC
       fmt.Println(dt.Unix()) // 0
    }

Does Go also has a distinction between naive/timezone-aware times? If not don't see why would expect something else. This is an issue because the distinction exists. Note it isn't bad that it does. There're actually arguments in favor of it. It's bad that can freely mix them.

Why would you ever want or need that?

Suppose you want to run a routine after 12h. That is now is 7 PM and want it to run tomorrow at 7 AM. Like if simply print times you get:

  t1 = datetime.now()
  t2 = t1 + datetime.timedelta(days=0.5)
  print(str(t1)) # '2023-11-19 19:00:00.000000'
  print(str(t2)) # '2023-11-20 07:00:00.000000'

is this English? also I am still not seeing a problem:

    package main
    
    import (
       "fmt"
       "time"
    )
    
    func main() {
       t1 := time.Now()
       t2 := t1.Add(12 * time.Hour)
       fmt.Println(t1) // 2023-11-19 15:14:16
       fmt.Println(t2) // 2023-11-20 03:14:16
    }

Ah, a grammar pedant. Haven't met one in a while.

>also I am still not seeing a problem

Try again setting your timezone to let's say NY and date at 2023-11-04. Oops.

"That is now is 7 PM"

"and want it to run tomorrow"

"Like if simply print"

none of these make sense

not sure what point youre trying to make, but youre failing:

    package main
    
    import (
       "fmt"
       "time"
    )
    
    func main() {
       t1 := time.Date(2023,11,4,7+12,0,0,0,time.FixedZone("EST", -5*3600))
       t2 := t1.Add(12 * time.Hour)
       fmt.Println(t1) // 2023-11-04 19:00:00 -0500 EST
       fmt.Println(t2) // 2023-11-05 07:00:00 -0500 EST
    }

No wonder since you failed to correctly specify NY timezone in first place. Here's a trivia, it wasn't UTC-5 on that date.

It does, which is great. Note however that Go times can be either wall-time or (wall-time, monotonic time), which have different semantics and are both represented by the same type.
