Using datenum for fraction of a second

I am looking for a ways to convert some dates into datenum, given their special format. My dates look as follows:
'2017-02-28 21:36:51'
'2017-02-28 21:36:51.5'
'2017-02-28 21:36:52'
'2017-02-28 21:36:52.5'
'2017-02-28 21:36:53'
'2017-02-28 21:36:53.5'
etc. etc. etc.
In other words, the format of the dates alternates, such that every other entry has an additional 500 milliseconds at the end of it. How can I convert these to datenum simultaneously, given their different formats? (or at least, how can I convert dates with .5 to datenum?). I cannot skip or ignore any of this data.
Thanks

Would datetime format instead of datenum format be acceptable?
datenum() tends to be more flexible in format conversion but sometimes datetime() is easier.

dates = {'2017-02-28 21:36:51'
'2017-02-28 21:36:51.5'
'2017-02-28 21:36:52'
'2017-02-28 21:36:52.5'
'2017-02-28 21:36:53'
'2017-02-28 21:36:53.5'};
temp = regexprep(dates, ':\d\d$', '$&.0', 'lineanchors');
Now temp is in consistent format
