I believe you might be under two misconceptions:
DateTime.millisecond
simply gets the millisecond fraction of the time between seconds.- In other words:
> import Time.DateTime exposing (..) > epoch |> addSeconds 2 |> addMilliseconds 123 |> millisecond 123 : Int
- So it makes sense that
epoch
yieldsmillisecond
as zero as well as all the other time components.
- In other words:
- You may be thinking of the "timestamp" which is also zero at the time of the
epoch
. This is discussed further below.
epoch
is not an endpoint in time; it is an arbitrary midpoint:
0
is the midpoint of the "Unix time" which also happens to be the start of 1970:
> epoch |> toTimestamp
0 : Time.Time
> epoch |> toISO8601
"1970-01-01T00:00:00.000Z" : String
Positive timestamps are more recent:
> epoch |> addYears 1 |> toTimestamp |> Debug.log "timestamp" |> fromTimestamp |> toISO8601
timestamp: 31536000000
"1971-01-01T00:00:00.000Z"
: String
And negative timestamps are further back in the past:
> epoch |> addYears -1 |> toTimestamp |> Debug.log "timestamp" |> fromTimestamp |> toISO8601
timestamp: -31536000000
"1969-01-01T00:00:00.000Z"
: String
Hope these are the answers you were looking for!
