Time-Base Queries are used in Stored Queries to make DateTime WHERE clauses possible. This is partly described in Unicenter Service Desk Modification Guide in the chapter 4. Customization of Queries and Messages.

You can use an exact date in the Time-Based Stored Queries or counted time using one of these 2 functions:

StartAtTime (timespan-name)

returns begin of the timespan's period.

EndAtTime (timespan-name)

returns end of the timespan's period.

Caution: Time-based stored queries recalculate timespans only when Trigger Time Milestone occured.


Timespans are simple string values (so must be enclosed in simple quotes leaded by backslash). They are defined in a special enumeration table, which can be out-of-the-box found in Administration tab -> Service Desk -> Application Data -> Codes -> Timespans.

Each timespan has 3 milestones which are connected to current time:

  • Start Time - beginning of the timespan period
  • End Time - end of the timespan period
  • Trigger Time - this milestone guides how often is time value recalculated in a stored query

You can define exact values (ie. 2008 for year, 4 for month, 3 for day and so on) into the time parts or relative differences against current value (ie. +1 or -5 and so on).

Out-of-the-box timespans

Here are list of predefined timespan names, but you can create new ones if you need. Examples assume actual date and time is 26.6.2008 11:07.
