ⓘ
Note

  • LOCALTIME was introduced in Firebird 3.0.4 and Firebird 2.5.9 as an alias of CURRENT_TIME. In Firebird 4.0, CURRENT_TIME returns a TIME WITH TIME ZONE instead of a TIME [WITHOUT TIME ZONE], while LOCALTIME returns TIME [WITHOUT TIME ZONE]. It is recommended to use LOCALTIME when you do not need time zone information.

  • LOCALTIME has a default precision of 0 decimals, where LOCALTIMESTAMP has a default precision of 3 decimals. As a result, LOCALTIMESTAMP is not the exact sum of CURRENT_DATE and LOCALTIME, unless you explicitly specify a precision (i.e. LOCALTIME(3) or LOCALTIMESTAMP(0)).

  • Within a PSQL module (procedure, trigger or executable block), the value of LOCALTIME will remain constant every time it is read. If multiple modules call or trigger each other, the value will remain constant throughout the duration of the outermost module. If you need a progressing value in PSQL (e.g. to measure time intervals), use Section 11.14, “'NOW'”.

Examples 

  |select localtime from rdb$database
  |-- returns e.g. 14:20:19.0000
  | 
  |select localtime(2) from rdb$database
  |-- returns e.g. 14:20:23.1200
