Date constants

(since 3.1.1, Bug #393094)

Grammar - two versions:

  • ISO format (KEXI default, recommended)
#yyyy-mm-dd#
  • US format (for compatibility, based on MSA default [1])
#mm/dd/yyyy#

Notes:

  • Both formats are not dependent on regional settings on the OS, they are always interpreted the same way
  • One or two digits are required for month and day, e.g. #2018-4-15# and #2018-04-1# are both valid dates
  • Four digits are required for year, e.g. #18-4-15# is invalid date
  • MSA's format such as #24 Dec 2014# is not supported.
  • Detailed grammar of VBA: https://msdn.microsoft.com/en-us/library/dn528865.aspx

Time constants

Grammar - two versions:

  • Full
#hh:nn:ss#
  • Short
#hh:nn#

Notes:

  • One or two digits are required; e.g. both #05:59:01# and #5:59:1# are time literals having the same value
  • 24 hour mode is only supported, that is no AM/PM suffix can be used

Date/Time constants

(since 3.1.1, Bug #393094)

Grammar:

#{date} {time}#

Where {date} is defined as for Date literals and {time} is defined as for Time literals.

Notes:

  • All notes regarding date and time format also apply to data and time parts of the value
