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
• All digits are required, including trailing zeros and century; e.g. #2018-4-15# and #18-11-11# are both invalid dates
• 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

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
