Pattern based dates 276 276 277 - ===13.7.1Pattern based dates===278 +Date and time formats are specified by date and time pattern strings based on Java's Simple Date Format. Within date and time pattern strings, unquoted letters from 'A' to 'Z' and from 'a' to 'z' are interpreted as pattern letters representing the components of a date or time string. Text can be quoted using single quotes (') to avoid interpretation. "''" represents a single quote. All other characters are not interpreted; they're simply copied into the output string during formatting or matched against the input string during parsing. 278 278 279 -Date and [[time formats>>doc:sdmx:Glossary.Time format.WebHome]] are specified by date and time pattern strings based on Java's Simple Date Format.
