Date and Time

The default format depends on the locale you use to run Cumulus.

When format is fixed it is noted.

Filter: Choose your criteria carefully.

Webtag	Function
<#date>	The current date.
<#metdate>	The current meteorological date. If you use midnight rollover, this returns same date as <#date> (above), but with a different default format. If using a 9am/10am rollover: After rollover time on current calendar date, this is same as <#date>, but with a different default format. Between midnight and 9am/10am the <#metdate> will return the date associated with previous calendar day, but will still return current time.
<#timeUTC>	The current UTC date/time rather than local date/time. Example result: 18:30 on 30 December 2009. If you want the local date and time, use next tag (below).
<#time>	The current time and date. Example result: 18:30 on 30 December 2009. If you simply wish the time, use next tag (below).
<#timehhmmss>	The current time (without date). Example format: 18:30:27. You can use output format specifiers to change the way the time is output, but any date specifiers are ignored.
<#minute>	The current time, just the minutes. Fixed format: 07 (cannot use output format modifiers).
<#hour>	The current time, just the hour. Fixed format: 07 (cannot use output format modifiers)
<#day>	The current day as a 2-digit number. Fixed format: 07 (cannot use output format modifiers).
<#dayname>	The current day as a word. For example, Monday
<#shortdayname>	The current day as a shortened word. Example format: Mon
<#month>	The current month as a 2-digit number. Fixed format: 07 (cannot use output format modifiers).
<#monthname>	The current month as a word. Example format: July
<#shortmonthname>	The current month as a shortened word. Example format: Jul
<#year>	The current year as a 4-digit number. Example format: 2009 (cannot use output format modifiers).
<#shortyear>	The current year as a 2-digit number. Example format: 09 (cannot use output format modifiers).
<#rollovertime>	The time that the logs rollover to the next day: 'Midnight', '9 am' or '10 am'
<#metdateyesterday>	The previous meteorological date. The default format depends on the locale you use to run Cumulus Note If you use midnight rollover, this returns same date as <#date>, but with a different default format. If using a 9am/10am rollover: * After rollover time on current calendar date, this is same as <#yesterday> (below), but with a different default format. * Between midnight and 9am/10am the date output by <#metdateyesterday> will be the calendar day before that returned by <#yesterday>, but the time returned is actual local time.
<#yesterday>	Yesterday's date.
<#update>	The date and time of the last web site update.
<#timeJavaScript>	The JavaScript Date object contains the number of milliseconds since 00:00:00.000 UTC on 1st January 1970, that date and time is known as the UNIX Epoch. Technical In JavaScript, you can use Math.floor(new Date().getTime()/1000.0) This getTime method returns the time in milliseconds. The web tag returns an integer (currently with 13 digits) representing the number of milliseconds since the UNIX epoch when the web tag was processed. It can be used in a script where you wish to re-express other times output by Cumulus MX into UTC (Coordinated Universal Time). Mac OS X uses 00:00:00.000 UTC on 1st January 2001 as the starting time and date for its millisecond count, so that is considerably lower. Note that UTC is calculated using 9192631770 times a particular transition time for Caesium 133 as a basis for 1 second. GMT (Greenwich Mean Time) is calculated on the basis that 1 second is 1/86400 of the time taken for a whole (day) rotation of the Earth. UT1 (or solar time) is calculated from various space measurements. Periodically, leap seconds are added to UTC to realign it with UT1, but these leap seconds are not added to the count of milliseconds represented by this web tag. Do be aware that some devices will use a 32 bit signed integer to represent this number, and that will stop working on 19 January 2038, the year 2038 problem for computing world.
<#timeUnix>	Unix tracks the number of seconds since the UNIX epoch. So this web tag can be used when you do not want the millisecond accuracy of the previous web tag. Like previous web tag this relates to UTC, so see details for that tag to find out more.
<#LastDataReadT>	The date/time data was last read from the station.
<#DaysSince30Dec1899>	Day count (gives whole and fractional part) Example: 41250.6523310301
<#recordsbegandate>	Date when records began.
<#DaysSinceRecordsBegan>	Day count since Cumulus records started.
<#DataDateTime>	This reflects the current date time with respect to the data. Use this web tag in things like Custom MySQL INSERT statements to pick up the historic data's date/time rather than the current clock date/time.
