getSeconds()
❑
getMilliseconds()
❑
toTimeString()
These methods return respectively the hours, minutes, seconds, milliseconds, and full time of the
specifi ed
Date
object, where the time is based on the 24-hour clock:
0
for midnight and
23
for 11 p.m.
The last method is similar to the
toDateString()
method in that it returns an easily readable string,
except that in this case it contains the time (for example,
“13:03:51
UTC”
).
