241 +Structure mapping allows non-[[SDMX>>doc:xwiki:Glossary.Statistical data and metadata exchange.WebHome]] compliant time values in source [[datasets>>doc:xwiki:Glossary.Data set.WebHome]] to be (% style="color:#2ecc71" %)mapped(%%) to an [[SDMX>>doc:xwiki:Glossary.Statistical data and metadata exchange.WebHome]] compliant time format.
234 234  
235 235  Two types of time input are defined:
236 236  
237 237  a. **Pattern based dates** – a string which can be described using a notation like dd/mm/yyyy or is represented as the number of periods since a point in time, for example: 2010M001 (first month in 2010), or 2014D123 (123^^rd^^ day in 2014); and b. **Numerical based datetime** – a number specifying the elapsed periods since a fixed point in time, for example Unix Time is measured by the number of milliseconds since 1970.
238 238  
239 -The output of a time-based mapping is derived from the output Frequency, which is either explicitly stated in the mapping or defined as the value output by a specific Dimension or Attribute in the output mapping. If the output frequency is unknown or if the SDMX format is not desired, then additional rules can be provided to specify the output date format for the given frequency Id. The default rules are:

251 251  In the case where the input frequency is lower than the output frequency, the mapping defaults to end of period, but can be explicitly set to start, end or mid-period.
252 252  
253 253  There are two important points to note:
254 254  
255 -1. The output frequency determines the output date format, but the default output can be redefined using a Frequency Format mapping to force explicit rules on how the output time period is formatted.
256 -1. To support the use case of changing frequency the structure map can optionally provide a start of year attribute, which defines the year start date in MM-DD format. For example: YearStart=04-01.

260 -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.
