Just updated GC to latest version on Google Play to, March 13th. I regularly have to enter manual activities. After this update, I can enter the date of an activity, but the option to enter the time of the activity went away? I can still enter time via the Web interface. Seems like a bug to me?
If I go in and EDIT an activity created from the webpage that already exists, then the time line is there. It seems to be only when creating a new manual activity via GC. Editting an existing activity created in GC also does not show the time of day line.
