CurTime() vs. TimeCurrent()

The MQL Manual provides the following descriptions for CurTime() and TimeCurrent() standard functions:

//-----------------------
datetime CurTime()
Returns the last known server time, number of seconds elapsed from 00:00 January 1, 1970.

Sample:

if(CurTime()-OrderOpenTime()<360) return(0);

//---------------------
datetime TimeCurrent( )
Returns the last known server time (time of incoming of the latest quote)
as number of seconds elapsed from 00:00 January 1, 1970.
Note: At the testing, the last known server time is modelled.

Sample:

if(TimeCurrent()-OrderOpenTime()<360) return(0);

The questions are:

1- Why is CurTime() standard function is shown in MQ4 files in black leters unlike other standard functions.

2- What is the difference between the above functions? When to use each on?

Thanks,

Although CurTime() works it is considered an obsolete function. Below is a partial list from the help files.


In further development of MQL4, some functions were renamed and moved from one group to another in order to systematize them better. The old function names are not highlighted or linked to the MetaEditor Dictionary. The old function names can be used since the compiler will accept them in a proper way. However, we strongly recommend to use the new names.
