You could run your application under valgrind + gdb/vgdb.
You can then put breakpoints at relevant places to trigger them at
t+1 and t+2.

You can then e.g. run with memcheck and have delta malloc info
being reported, using the memcheck monitor command leak_check.
This command can show the delta "alloc/free" since the previous
call.
