DateTime++ : An easy to use C++ library for date-time calculations

Features / Roadmap

v1.0.0 General Functions working

• get / set DateTime values
• set DateTime values to current local time
• set DateTime values to current UTC time
• add compare operators == != < to compare DateTimePP objects
• get info if year is leapYear
• get number of days of month (consider leapYear)
• get number of days of year (consider leapYear)
• get number of days between two dates (consider leapYear)
• get current time as unix time string
• do standard tests for toUnixTime()
• do extended tests for toUnixTime()
• throw exceptions if unixTime is not used properly
• document every file and every function
• do code-review before release

v1.1.0 add toString, fromString functions

• add toString function that can write out the date-time values as a formatted string
• add fromString function that can read the date-time values from a formatted string
• add function deletePaddingZeros()

v1.2.0 Make class canonical

• add test-cases for new functions of v1.1.0
• add copy-constructor
• add standard constructor
• add assignment operator =
• add comparison operators > < <= >=
• add more testcases to already implemented operators
• add comparison operators =~ =~~ =~~~

v1.3.0

• throw exceptions if values are used that not work in the gregorian calender
• throw exceptions if DateTimePP objects don't use the same timezone
• add exceptions to make all functions invalid-parameter-save
• add word "Error" to all exceptions
• check if all functions are tested, e.g. date() is not
• document exceptions

v1.4.0 time-zone calculations

• move DateTimeObjects into new time-zone
• add style-guide, license, contribution files...

v1.5.0 arithmetics with DateTimePP objects

• add or subtract DateTimePP objects
• add operators + - += -=

v1.6.0 weekday / calenderweek calculation

• get calenderweek by date
• get weekday by date

v2.0.0 negative unix time, extended days between dates

• support negative unix times
• check for which numbers numberOfDaysBetweenTwoDates and other functions run into datatype-out-of-range-problems
• either solve the out range problems or throw exceptions in these cases

v2.1.0 more test-cases ensuring typical pitfalls of date-time-calculation

• ensure winter time works
• ensure leap year works
• making all functions non-gregorian-time-save

v3.0.0

• support nseconds in time
