I am using the following schedule code however it is not rebalancing on the 1st day and 15. It is rebalancing the second when the dates are 2014-01-01 to 2014-12-31 

2014-01-02  
2014-01-15  
2014-02-03  
2014-02-14  
2014-03-03

  schedule_function(rebalance,  
                      date_rule=date_rules.month_start(),  
                      time_rule=time_rules.market_open())

  schedule_function(rebalance,  
                      date_rule=date_rules.month_start(days_offset=10),  
                      time_rule=time_rules.market_open())

For 2014, January, the 1st was not a trading day. the 2nd was the first trading day of the month. The 15th was the 10th trading day of January.

For February, 1st and 2nd was saturday/sunday, so the 3rd was first trading day. From this point, the 10th trading day was the 14th.

For March, same thing happened: 1st and 2nd was weekend, so 3rd was first trading day.

Looks okay to me?

Still it is doing something weird in other time frames like January 2011 look. Also I have noticed that sometimes it does the rebalancing on second or third date instead of the first day. It is driving me nuts! I think that Quantopian schedule function is not working properly

That's right, the transactions are shown in your local time zone (as determined by your computer settings)
