from
Creates a Timestamp from the given Instant.
Instant is based on nanosecond precision, while Timestamp is based on microseconds. Since Timestamp has less precision, any additional nanoseconds in the Instant will be truncated. This does not result in a loss of precision relevant to Timestamp, as it cannot store nanoseconds.
Return
a Timestamp that represents the same point in time as the given Instant, truncated to microsecond precision
Parameters
instant
an Instant to create a Timestamp from
