I have a feeling you're overthinking this; a simple spreadsheet will be easiest. Ignore the integration bit for now and just start by tracking your time/tasks. Do it for a week and see what you think.
Personally, at the end of each work day, I use the spreadsheet method to record my progress for that day. I have one column for the date and one for a 1 or 2-sentence summary or notes about what I did during the day. I've been doing this for years and it's nice to have a historic "captain's log" of my work.
It would be easy to add more columns to this type of spreadsheet to break the day into hourly increments or even 15 minute increments. Any shorter than 15 mins and it's too easy to get frustrated by the interruption of needing to write the log. Hourly would probably be more realistic.
In Google Sheets, use command-shift-colon to do a timestamp.
