I’ve got two entities, one that contains a string which is ultimately a time, but its represented simply as “4:30 PM” (the time a ferry leaves). I’ve got another entity from the google maps travel time tracker, who’s value is merely ‘35’ (minutes, but the value is just straight 35)
I’m trying to calculate the time the ferry leaves, minus the trip time, to essentially tell me when i need to leave by.
The trouble is, using date and time functions, these values are not interpreted properly as timestamps of course, and even trying to convert them to one with strptime() etc will fail, because they dont contain a date, only hours and minutes, or minutes.
Anyone have suggestions on how I might subtract ‘35’ from '4:30 PM" in this example, taking into account that it is in fact a time?
