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
}
- skitter 3y agoIt 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.
- forgotpwd16 3y agoDoes 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.

- forgotpwd16 3y agoSuppose 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'

Like if simply print times you get 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 }

- 38 3y ago> Ah, a grammar pedant. Haven't met one in a while. "That is now is 7 PM" "and want it to run tomorrow" "Like if simply print" none of these make sense > Try again setting your timezone to let's say NY and date at 2023-11-04. 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 }
- forgotpwd16 3y ago>not sure what point youre trying to make, but youre failing 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.
