Can I write start times in HH:MM:SS format instead of total seconds?

[dgrrr]

If I want a hyperlink to start playing the file "C:\filename.mkv" at 29 minutes, 54 seconds into the video, is there a way I can write the link in hours:minutes:seconds instead of totalling the seconds as in the following?

"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" --start-time=1794 "C:\filename.mkv"

In other words, it would be easier if I could write the "1794" as "00:29:54", or "0h29m54s", like in youtube links.
