Thread: Unix timestamp , unix timestamp with microseconds ?

Unix timestamp , unix timestamp with microseconds ?

From
"NTPT"
Date:
 I read the documentation well (PG 7.3.3 ) , it seems that there is not a native support for  data type  UNIX TIMESTAMP and "unix  timestamp expressed as microseconds" 
 
ie  there it is  impossible to direct insert and select  
 
 seconds_from _Epoch 
 seconds_from _Epoch (period) microseconds_part
 seconds_from _Epoch(no period here)microseconds_part
 
without  some data conversion ?
 
Thanx for help
