How many seconds has passed today?
Write a function
getSecondsToday() that returns the number of seconds from the beginning of today.
For instance, if now
10:00 am, and there was no daylight savings shift, then:
getSecondsToday() == 36000 // (3600 * 10)
The function should work in any day. That is, it should not have a hard-coded value of “today”.
To get the number of seconds, we can generate a date using the current day and time 00:00:00, then substract it from “now”.
The difference is the number of milliseconds from the beginning of the day, that we should divide by 1000 to get seconds:
An alternative solution would be to get hours/minutes/seconds and convert them to seconds:
