Another way:
select
(cast(current_timestamp as date) - date '1970-01-01') * 86400000.
+ (extract(hour from current_timestamp) * 3600000)
+ (extract(minute from current_timestamp) * 60000)
+ cast(extract(second from current_timestamp) * 1000 as int) as millisecs
,cast(millisecs / 1000 as int) as secs
,cast(date '1970-01-01' + (secs / 86400) as timestamp(3))
+ ((secs mod 86400) / 3600 * interval '1' hour)
+ (((millisecs / 1000.000) mod 3600) * interval '1' second)
;
