The difference to datetime.timedelta is, that this class handles also differences given in years and months. A Duration treats differences given in year, months separately from all other components. A Duration can be used almost like any timedelta object, however there are some restrictions: * It is not really possible to compare Durations, because it is unclear, whether a duration of 1 year is bigger than 365 days or not. * Equality is only tested between the two (year, month vs. timedelta) basic components. A Duration can also be converted into a datetime object, but this requires a start date or an end date. The algorithm to add a duration to a date is defined at http://www.w3.org/TR/xmlschema-2/#adding-durations-to-dateTimes rc t|tstt|}t| tstt| } ||_| |_t ||||||||_dS)zN Initialise this Duration instance with the given parameters.

TODO: there is some weird behaviour in date - timedelta ... if timedelta has seconds or microseconds set, then date - timedelta != date + (-timedelta) for now we follow this behaviour to avoid surprises when mixing timedeltas with Durations, but in case this ever changes in the stdlib we can just do: return -self + other instead of all the current code rYrrZr[)r+rr)r/r]r.r^r-r_r&rr%r'r\r`rrarb) r0rctmpdurrerfrgrhrirjs r__rsub__zDuration.__rsub__sR eY ' ' !ZZF!FMD=  $*%%0022 ;$+&&1133 ; ":;;;{T[0H&xB77OE8j4:-5G'::Gy7"" MM\\XCKK"E4;& &    D sC=D// D<;D<ct|tr:|jdz|jz|jdz|jzkr|j|jkrdSdS|jdkr|jdkr |j|kSdS)z If the years, month part and the timedelta part are both equal, then the two Durations are considered equal. rTFrr+r)r.r-r/r0rcs r__eq__zDuration.__eq__s eX & & *r/DK/+"U\133 ,,t5 :??t{a//;%' 'urct|tr:|jdz|jz|jdz|jzks|j|jkrdSdS|jdkr|jdkr |j|kSdS)z If the years, month part or the timedelta part is not equal, then the two Durations are considered not equal. rTFrrvrws r__ne__zDuration.__ne__'s eX & & *r/DK/+"U\133 ,,t5 :??t{a//;%' 'trNcr||td||td|||z|z S|||z z S)z Convert this duration into a timedelta object.
