Help for review timeframe

/review output may be limited to a specific timeframe or number of events:

  all:              The entire review buffer.                         
  session:          Starting from your last login.                    
  detached:         Starting from your last detach.                   
  old:              Ending at your last detach.                       
  today:            Today, based on server time.                      
  yesterday:        Yesterday, based on server time.                  
  tag:              Starting from your last /review set.              
  last num[e|i|u]:  The last num events, images, or URLs.             
  last time_range:  The last time_range up to now.                    
  prev time_range:  The time_range before where the last review began.
  next time_range:  The time_range after where the last review ended. 

Here, time_range is a number followed by a single letter specifying the units (s
for seconds, m for minutes, h for hours, d for days, w for weeks, or y for 
years. Multiple of these can also be appended together (e.g. 1h30m).

Note that /review detached can also be used with a discussion to see events that
happened in the discussion while you were disconnected.

The command /review set can be used to set the review tag to the current time 
and this can be used a starting point for a later review by using the tag 
option. /review set accepts no other options.

Once the tag is set, the prev and next options can be used to repeatedly move 
backward and forward through the review buffer base  on the requested amount of 
time, updating the tag each time to where the review left off.
