or just use coalesce. Here is an example how to do an in-place update:

julia> timestamps = [Time(12, 30),Time(12, 30), missing, missing, Time(15,30), Time(16, 30)]
6-element Vector{Union{Missing, Time}}:
 12:30:00
 12:30:00
 missing
 missing
 15:30:00
 16:30:00

julia> timestamps .= coalesce.(timestamps, Time(12))
6-element Vector{Union{Missing, Time}}:
 12:30:00
 12:30:00
 12:00:00
 12:00:00
 15:30:00
 16:30:00
