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.

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
