• date: grabs the date part of a date time point value
• time: grabs the time part of a date time point value
• dayToNumbervalue
• dateTimeAdd: add a duration (hrs, mins, or secs) from a dateTime
• dateTimeSub: substract a duration (hrs, mins, or secs) from a dateTime
• dateToNumber: converts the date into a number
• dayToStringdateToString: converts a part of date into a string
• dtToDtAdd: add one dateTime to another dateTime; results in a duration of minutes or seconds
• dtToDtSub: subtract one dateTime from another dateTime; results in a duration of minutes or seconds
• now: get the current dateTime for the host
• siteDateTime: get the current data date and time for the site associated with the target Ref of the bline program

These are the main blocks, but there are 2 other blocks that provide specific operations for the time:

• dateTimeAdd: add a duration from a dateTime. (minutes are the assumed unit)
• dateTimeSub: substract a duration from a dateTime (minutes are the assumed unittime: extracts just the time part of a date time value
• timeToMinutes: converts a time value to a number of minutes 
• timeToTimeAdd: add one time to another time; results in a duration of minutes or seconds
• timeToTimeSub: subracts one time from another time; results in a duration of minutes or seconds

Some blocks have inputs or results in dateTime format, while others in simple time format. Blocks that require a time format input might not work if a dateTime value is used as the input.

dateTime example:  2019-07-04  14:39:15:149   (date and time with milliseconds) 

time example: 14:39:15  (just hours:minutes:seconds)

The Blocks can be found in the B-Line app, after creating a new programBlock Library in the Time group.
