===== Library =====

LIB\CORE

===== Version =====

V1.0

===== Description =====

The block converts time and date to total seconds (starting at 1.1.1970, 0:00). Another output is the current weekday.

===== Inputs =====

|Input|Type|Description|Default value|
|SEC  |SINT|Seconds    |0            |
|MIN  |SINT|Minutes    |0            |
|HOUR |SINT|Hours      |0            |
|DAY  |SINT|Days       |0            |
|MON  |SINT|Months     |0            |
|YEAR |INT |Years      |0            |

===== Outputs =====

|Output|Type |Description                                         |
|TOT   |UDINT|Number of seconds since 1.1.1970, 00:00 UTC         |
|WDAY  |SINT |Weekday (//0// = Sun, //1// = Mon, ..., //6// = Sat)|

===== Function =====

The block converts time and date to total seconds (starting at 1.1.1970, 0:00). Another integer output, //wday,// defines the current day of week (//0// = Sunday, //1// = Monday, ..., //6// = Saturday). For example, 1.1.1970 01:00 – one hour after the reference time start (i.e. //sec=0//, //min=0//, //hour=1//, //day=1//, //mon=1//, //year=1970//) - the outputs are //tot=3600//, and //wday=4//.

The block, together with B98, is used as an auxiliary block for various time/date conversions, calculating of time spans etc.
