shide 0.3.0

• New seq.jdatetime() generates regular sequences of Jalali date-times.

• Rounding family of functions (sh_floor(), sh_ceiling() and sh_round()) now accept jdatetime inputs.

• Fixed an issue where jdatetime objects did not span the entire predefined value range.

• Due to changes in upstream packages, negative years such as -1000-01-01 will no longer parse with %Y-%m-%d, and instead require %5Y-%m-%d or %5F to capture the - prefix (#8).

shide 0.2.1

• Default formatting for jdatetime objects is changed to conform to default R behavior.

• jdate and jdatetime vectors are printed more nicely in tibbles.

• Rounding family of functions (sh_floor(), sh_ceiling() and sh_round()) now accept multi-unit values for unit argument.

• jdatetime() and jdatetime_make() now support ambiguous time resolution strategies via ambiguous argument (ambiguous times occur during a repeated interval when the clock is adjusted backwards during the transition from DST to standard time).

• Fixed a bug regarding casting of jdatetime to jdate (#4).

shide 0.2.0

• New sh_year_is_leap() determines if a Jalali year is a leap year.

• New accessor and replacement functions are added to get/set the components of Jalali date-time objects.

• New family of functions for rounding Jalali dates to a specific unit of time:

  • sh_floor() rounds a jdate object down to the previous unit of time.

  • sh_ceiling() rounds a jdate object up to the next unit of time.

  • sh_round() rounds a jdate object up or down, depending on what is closer.

• New seq.jdate() generates regular sequences of Jalali dates.

• as.POSIXlt() now errors with jdate and jdatetime input. In order to cast jdate and jdatetime to POSIXlt, first, they should be converted to Date and POSIXct respectively.

• jdate() now truncates numeric input toward zero before generating a jdate object.

• jdatetime() now truncates numeric input toward zero before generating a jdatetime object.

• Fixed a bug where names were dropped after calling format() upon a jdate or jdatetime object.

shide 0.1.2

• Initial CRAN submission.
• Added a NEWS.md file to track changes to the package.
