15a3694cca more complete unit test pass 2011-09-25 19:25:54 +02:00
9bd96a1b19 time-entities refactoring: Duration isn't an Offset
removed that inheritance relation; it was a typical
example of abusing inheritance and violated the
Liscov substitution principle. It is sufficient
to allow promotion of an offset into a Duration.
Note: Duration is the time metric

eed2b0f320 time::Control simple unit test pass 2011-09-25 19:25:52 +02:00
ef126283eb add symbolic constant for "neutral" time.
Note: it's rather arbitrary choosen,
because any time grid can define its own origin.
You must not assume that the origin of any time axis
is located at Time::ZERO !!

af9c799fc8 Fix time quantisation to circumvent the precision problem
required to re-arrange several functions in order
to use the new util::floordiv and to get all relevant
calculations into time.h

52eb4c4709 set an explicit artificial limit on the allowed time range
this is the first building block in an attempt to
protrect against time wraparound. The intention is
not to be airtight, but practically effective.

A really airtight solution would require writing
our own SafeInt class

3cf9974211 provide unary minus to flip a TimeVar around origin 2011-01-13 03:36:11 +01:00

now passes Compiler and Linker again

c40ba74bc6 WIP clarify ambiguity with fractional seconds
They are *not* intended to stand-in for gavl_time_t
Indeed, Time values should be handled as opaque

09d400d5bc put asside the existing "lumitime" to build a new hierarchy from scratch
existing code will still use lumitime.hpp for now
while we're about to reorganise time handling altogether

784b094fa7 fix compilation problems with draft code 2010-12-26 23:00:34 +01:00
f18226e8ac WIP start drafting simple time values, offsets and intervals
questions: what is mutable / immutable?
what is the distinction between TimeValue and Time ?
what conversions make sense?
what mutations / operators to support?

cce72e611e WIP: new namespace and compliation units for time quantisation
namespace lib::time
lumitime.cpp will define the basic time wrapper
quantiser.cpp the grid alitnment and formatting wrapper

header for
- timevalues / ranges
- quantised time valuse
- timecode valuse

"lumitime.hpp" will contain the interface facilities
