/*
 * generates a timestamp string suitable for inserting into a database, the timestamp
 * argument must be a valid POSIX calendar time.
 *
 * pgsql: https://www.postgresql.org/docs/9.1/datatype-datetime.html
 *   - "For timestamp with time zone, the internally stored value is always in UTC
 *      (Universal Coordinated Time, traditionally known as Greenwich Mean Time, GMT).
 *      An input value that has an explicit time zone specified is converted to UTC
 *      using the appropriate offset for that time zone.
 *
 *      If no time zone is stated in the input string, then it is assumed to be in the
 *      time zone indicated by the system's timezone parameter, and is converted to
 *      UTC using the offset for the timezone zone. When a timestamp with time zone
 *      value is output, it is always converted from UTC to the current timezone zone,
 *      and displayed as local time in that zone. To see the time in another time zone,
 *      either change timezone or use the AT TIME ZONE construct (see Section 9.9.3).
 *
 *      Conversions between timestamp without time zone and timestamp with time zone
 *      normally assume that the timestamp without time zone value should be taken or
 *      given as timezone local time."
 *
 * mysql: https://dev.mysql.com/doc/refman/8.0/en/datetime.html
 *  - "MySQL converts TIMESTAMP values from the current time zone to UTC for
 *     storage, and back from UTC to the current time zone for retrieval."
 *
 * oracle: https://docs.oracle.com/cd/B19306_01/server.102/b14225/ch4datetime.htm#i1006050
