InstantnowtoEpochMilli
InstantnowtoEpochMilli is a term used to describe obtaining the current moment expressed as the number of milliseconds since the Unix epoch. The Unix epoch is defined as 1970-01-01T00:00:00Z, and the resulting value is commonly used for time stamping, duration calculation, and time storage in logs and databases.
In Java, the canonical approach is Instant.now().toEpochMilli(), which returns a long representing the current time in
The returned value increases with real time but can jump if the system clock is adjusted (for
Implementation notes: the precision of the value depends on the underlying clock and platform. In Java, toEpochMilli
