st: algorithm to allocate time

Hi everyone,
I'm working with pilot time-use survey (TUS) data from my country.
Unlike in other TUSs where a primary activity is specified, in our
case all activities and time are listed without regard to which
activity is the primary activity for a given time. I need to allocate
time spent on multiple activities to each of these activities, such
that time spent on all activities will equal 24 hours for a day.
Without additional information, I am thinking of just splitting the
time spent on multiple activities equally among activities. However I
have no idea how to automate it in Stata. A sample of the data is as
follows:
id startampm starthour startminute endampm endhour endminute actvty
1 am 10 1 am 10 30 911
1 am 10 15 am 11 45 832
1 am 11 0 am 11 30 465
1 am 11 30 pm 1 45 223
1 pm 1 30 pm 2 30 911
where
id - respondent id
*ampm - if activity (started/ended) in am or pm
*hour - hour activity (started/ended)
*minute - minute activity (started/ended)
actvty - is a number code of the activity done
I hope to hear your suggestions. Thank you in advance.
With best,
Michael
