The BDE team is pleased to announce that the BDE Release 3.1 was completed on Monday, May 15, 2017

The bdlt::Time and bdlt::DatetimeInterval classes have been enhanced to now provide microsecond resolution. (Previously, those classes provided millisecond resolution.)

Users of bdlt::Time and bdlt::DatetimeInterval must be aware of two other changes that are concomitant with the increased precision:

• The size of each class has increased by four bytes:

  Class	Old Size	New Size
  bdlt::Time	4 bytes	8 bytes
  bdlt::DatetimeInterval	8 bytes	12 bytes

• The output format of the print method and free operator<< methods now show six decimal places for the time value. (Previously, three decimal places were shown.)

The encoder/decoder classes for the BER, JSON, and XML protocols can now support microsecond resolution (i.e., up to six places to the right of the decimal point). See the datetimeFractionalSecondPrecision attribute of the encoder options classes for each protocol. The default value for encoding precision depends on the protocol.

The bdld::Datum class now implicitly handles time values with microsecond resolution.

The bdlt_calendarutil component provides a suite of functions for date calculations based on a specified bdlt::Calendar object.
