+:warning: Please note that:

+- on native platforms, *microseconds* unit is used.
+- on web platform, *milliseconds* unit is used (due to JS limitation with dates).
+
+:bulb: Also a `DateTime<Local>` will always be translated into local time of the device, which might not be what you want if you expect them to be sent *as-is*.
+
+> In that case, you could implement it in your codebase by sending a `u32` (timezone offset) alongside the `i64` (timestamp) over the wire, or open a issue / PR here to further discuss it. The reason why this choice was originally made is to have all `DateTime<Utc>`, `DateTime<Local>` and `NaiveDateTime` been represented by a single `i64`.
