Before you merge, you need to know that all datetime arrays have a date and time associated with them, even if that information is not displayed due to the formatting applied.
d = datetime('today')
d = datetime
22-Feb-2022
d.Format = 'HH:mm:ss'
d = datetime
00:00:00
The point, then, is to first check your format to make sure the information is not already there. If there truly is no date information associated with the time data, then it is best to import this data as a duration instead of a datetime.
As a duration, you could then just add the date and time together.
a = datetime('today')
a = datetime
22-Feb-2022
t = duration(19,20,3)
t = duration
19:20:03
dt = a+t
dt = datetime
22-Feb-2022 19:20:03
However, if your time is a datetime, you must extract just the time of day before adding it to your date.
f = datetime('today')
f = datetime
22-Feb-2022
g = datetime('now','Format','HH:mm:ss')
g = datetime
14:03:09
Y = f+timeofday(g)
Y = datetime

There might be something more efficient but this should work:
dt = datetime(strcat(string(date')," ",string(time')))
