Convert string to datetime ignore timezone

[NN]

Hi Everyone,
I have a datetime string with Timezone in it
val='2021-08-05T14:02:57.777-05:00'
Is there a way to convert this to datetim19. ignoring the timezone.
so that the time remains 14:02:57

Thanks..

How about

data test;
   val='2021-08-05T14:02:57.777-05:00';
   dt = input(val, anydtdtm19.);
   format dt datetime19.;
run;
