#CHROME HISTORY VIEW BY DATE MAC#
You may recall I blogged about Apple's Mac Absolute Time in February. Unfortunately, there are more time formats out there than these. Of course, this is because you have to count backwards from 1970 to 1601! With this information, we can convert Chrome time in SQLite like this: The commands calculate the number of seconds between unixepoch time (1970) and the subsequent date (Chrome time base, 1601). In both commands above, the "%s" represents unixepoch time. With SQLite itself, or with the Unix date command. To calculate local time, Chrome time has to be converted to seconds by dividing by one-million, and then the seconds differential between 00:00:00 and 00:00:00 must be subtracted. Though it is also a microsecond calculation, its base time is 00:00:00. What I do know, is that Chrome time IS NOT the same as PRTime. EDIT: I have learned the name for the Chrome's format is Webkit format). If there is an official name for Chrome time, I don't know it. Sqlite> SELECT datetime(time/1000000, 'unixepoch', 'localtime') AS time FROM table This can be done by dividing the value by one-million. The timestamp needs to be converted to unixepoch format before it can be converted to local time through the SQLite datetime() function. PRTime is the number of microseconds since 00:00:00. The extra seven digits in the Chrome timestamp brought to mind Firefox PRTime.
#CHROME HISTORY VIEW BY DATE FULL#
Without it, the column takes the full datetime() function as the column name which is a bit ugly and confusing to recipients of the data. The "AS time" displays the column label as "time".

" time" is the name of the field containing the (currently) 10-digit date string, e.g., "1307078210", and " table" is the name of the table containing the time field. Sqlite> SELECT datetime(time, 'unixepoch', 'localtime') AS time FROM table It can be converted in a SQLite statement with the datetime() function thusly: Unixepoch time is the number of seconds elapsed since 00:00:00. Fortunately, there’s a quick and easy workaround that will enable you to apply some advanced search options to your Chrome browser’s history page. You cannot even search your Chrome history by date or tags. However, the Chrome timestamps are 7 digits longer than unixepoch time. However, there’s no easy way to sort out your history list. The timestamp in the History SQLite databases look like unixepoch time at first glance, but they are not. I had occasion to work with Google Chrome histories today.
