µC/Clk is a module that implements a Year 2000 compliant clock/calendar module. The clock/calendar module offers the following features:

• Maintains time in seconds starting from 2000/01/01 (January 1st, 2000) at 00:00:00 UTC until 2134/12/31 (December 31st, 2134) 23:59:59 UTC; but supports conversions to/from two other timestamps:

  • NTP (Network Time Protocol) timestamps, starting from 1900/01/01 (January 1st, 1900) at 00:00:00 UTC until 2034/12/31 (December 31st, 2034) 23:59:59 UTC;

  • Unix timestamps, starting from 1970/01/01 (January 1st, 1970) at 00:00:00 UTC until 2104/12/31 (December 31st, 2104) 23:59:59 UTC.

• Allows your application to obtain timestamps to mark the occurrence of events. A µC/Clk timestamp is a copy of its internal timestamp.

• Allows your application to get the current date and time into a structured data type named CLK_DATE_TIME containing Year, Month, Day, Day-of-Year, Day-of-Week, Hour, Minute, Second, and Timezone Offset. Can convert timestamps to dates/times or vice versa.

• Allows your application to get and set the clock date/time using any of the supported timestamps or a CLK_DATE_TIME structure and allows conversion to/from all supported timestamps and the CLK_DATE_TIME structure.
