I'm having trouble converting values like
08:49:46 PM10:30:46 AM
from Character Column to Numeric h:m:s 24h format.
I would like to run the conversion without JSL and without depending on Operation system time format.
Change your format to Duration, or Format( "hr:m:s", 13, 0 ). Note the other format with AM and PM is Format("h:m:s",13,0)
